They might also develop a smell similar to putty or nail polish remover, but that&rsquo;s not always easily noticeable.<\/p>\n\n\n\n<p>In other words, you usually need to taste a nut or two to learn if they&rsquo;re rancid or not.<\/p>\n\n\n\n<p><strong>Can rancid nuts be saved?<\/strong> No. The damage has been done, and you can&rsquo;t reverse the process. If yours are rancid, throw them out.<\/p>\n\n\n\n<p>Now, going rancid is a process that takes weeks, if not months, so it&rsquo;s not like your macadamias will be nice and buttery one day and bitter the next day. There&rsquo;s a spectrum of flavors, and you need to decide at which point the nuts aren&rsquo;t good enough to eat.<\/p>\n\n\n\n<p>The good news is that rancid nuts aren&rsquo;t&nbsp;<a href=\"https:\/\/ucfoodsafety.ucdavis.edu\/sites\/g\/files\/dgvnsk7366\/files\/inline-files\/44384.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">unsafe to eat<\/a>, so eating one or two to learn if they&rsquo;ve gone bad won&rsquo;t get you in trouble. But consuming a whole pack of rancid macs isn&rsquo;t a good idea either, as they aren&rsquo;t particularly&nbsp;<a href=\"https:\/\/www.healthline.com\/nutrition\/raw-vs-roasted-nuts\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">good for you<\/a>.<\/p>\n\n\n\n<p>Of course, rancidification isn&rsquo;t the only possible reason you might need to toss your macadamia nuts.

For example, maybe you&rsquo;ve kept them in an open container near foods that give off a strong smell?<\/p>\n\n\n\n<p><a href=\"https:\/\/ucfoodsafety.ucdavis.edu\/sites\/g\/files\/dgvnsk7366\/files\/inline-files\/44384_0.pdf\">Shelled nuts readily a<\/a><a href=\"https:\/\/ucfoodsafety.ucdavis.edu\/sites\/g\/files\/dgvnsk7366\/files\/inline-files\/44384_0.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">b<\/a><a href=\"https:\/\/ucfoodsafety.ucdavis.edu\/sites\/g\/files\/dgvnsk7366\/files\/inline-files\/44384_0.pdf\">sorb smells<\/a>, so that&rsquo;s quite probable.<\/p>\n\n\n\n<p>Now, what if your macadamia nuts aren&rsquo;t spoiled, but taste kind of meh?<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"using-stale-macadamias\">Using Stale Macadamias<\/h3>\n\n\n<p>Macadamia nuts going stale isn&rsquo;t the end of the world. There are still a couple of ways you can use them. Some examples include:<\/p>\n\n\n\n<ul><li><strong>Roasting them.<\/strong>&nbsp;Roasting nuts is the tried and tested way to bring out more flavor and help freshen old nuts a bit. You can even add some spices to adjust their flavor even further.&nbsp;<a href=\"https:\/\/www.australian-macadamias.org\/consumer\/how-to-roast-macadamias-perfectly-every-time\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Here&rsquo;s a guide<\/a>&nbsp;to get you started.<\/li><li><strong>Making nut butter.<\/strong>&nbsp;If you&rsquo;re into nut butters (think <a href=\"https:\/\/www.canitgobad.net\/can-peanut-butter-go-bad\/\">peanut butter<\/a>, almond butter, and to some extent <a href=\"https:\/\/www.canitgobad.net\/can-nutella-go-bad\/\">Nutella<\/a>),&nbsp;<a href=\"https:\/\/thecoconutmama.com\/homemade-macadamia-nut-butter\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">making your own using macadamias<\/a>&nbsp;is an option. Of course, since the nuts taste stale, I suggest being liberal with spices and maybe even sweetening the whole thing a bit.<\/li><li><strong>Folding them into baked goods.<\/strong>&nbsp;Almost any baked good could benefit from some roughly chopped nuts. Add the macs when the batter is ready, give it a quick swirl, and get baking.<\/li><li><strong>Toping desserts.<\/strong>&nbsp;Top your store-bought plain ice cream with some chopped macadamias for extra flavor. If you&rsquo;re worried the nuts will spoil the whole thing, do a test tun with a tablespoon of ice cream topped with a sliver or two.<\/li><li><strong>Making a salad.<\/strong>&nbsp;All the flavors in salads tend to blend together, so you probably won&rsquo;t notice that the nuts you used were stale, but they&rsquo;ll still add a nice crunch. For best results, choose a recipe that calls for macadamias.<\/li><\/ul>\n\n\n\n<p>Last but not least,&nbsp;<strong>roasting stale macadamias is always a good idea<\/strong>, whether you want to eat them as a snack, blend them into nut butter, or chop and add to something you bake.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><noscript><img decoding=\"async\" loading=\"lazy\" width=\"600\" height=\"400\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop.jpg\" alt=\"Macadamia nuts on a wooden scoop\" class=\"wp-image-1766\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop.jpg 600w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\"><\/noscript><img decoding=\"async\" loading=\"lazy\" width=\"600\" height=\"400\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop.jpg.webp\" alt=\"Macadamia nuts on a wooden scoop\" class=\"wp-image-1766 lazyload\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop.jpg.webp 600w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop-300x200.jpg.webp 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" data-pin-media=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Macadamia-nuts-on-wooden-scoop.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><figcaption>Macadamia nuts on a wooden scoop<\/figcaption><\/figure><\/div>\n\n<h2 class=\"wp-block-heading\" id=\"how-long-do-macadamia-nuts-last\">How Long Do Macadamia Nuts Last?<\/h2>\n\n\n<p><strong>Shelled macadamia nuts last about&nbsp;<a href=\"https:\/\/ucanr.edu\/datastoreFiles\/234-2753.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">5 months at room temperature<\/a>, 12 months in the fridge, and more than 2 years in the freezer.<\/strong>&nbsp;In-shell macadamias&nbsp;<a href=\"https:\/\/postharvest.ucdavis.edu\/Ask_the_Produce_Docs\/?uid=178&amp;ds=800\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">keep about 25-50% longer<\/a>, which means more than half a year at ambient temperature and more than a year in the fridge.<\/p>\n\n\n\n<p>Of course, if the temperature where you store your macs is way more than 68&deg;F (20&deg;C), they might not keep for the whole five months.

More on that in a moment.<\/p>\n\n\n\n<p>Now, the periods above are only rough guidelines. The same is true for any date printed on the label of bagged macadamia nuts. These aren&rsquo;t expiration dates but rather educated guesses on how much it might take before the nuts rapidly lose quality.<\/p>\n\n\n\n<p>In other words, you shouldn&rsquo;t pay that much attention to the best-by date on the label. Instead, base your decision on whether the macs are safe to eat or not on their quality.<\/p>\n\n\n\n<p>The best the printed date could do for you is to inform you: &ldquo;hey, these are quite old, so they might taste stale or even be rancid already.&rdquo; But you won&rsquo;t know for sure until you actually check them for <a href=\"#spoilage\">signs of spoilage<\/a>.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><noscript><img decoding=\"async\" loading=\"lazy\" width=\"600\" height=\"400\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix.jpg\" alt=\"Nuts mix\" class=\"wp-image-1768\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix.jpg 600w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\"><\/noscript><img decoding=\"async\" loading=\"lazy\" width=\"600\" height=\"400\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix.jpg.webp\" alt=\"Nuts mix\" class=\"wp-image-1768 lazyload\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix.jpg.webp 600w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix-300x200.jpg.webp 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" data-pin-media=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-mix.jpg\" id=\"mv-trellis-img-4\" data-trellis-processed=\"1\"><figcaption>Peanuts, walnuts, almonds, hazelnuts, Brazil nuts and Macadamias side by side<\/figcaption><\/figure><\/div>\n\n<h2 class=\"wp-block-heading\" id=\"storage\">How to Store Macadamia Nuts<\/h2>\n\n\n<p><strong>Store macadamia nuts sealed tight and in a cool and dry area.<\/strong>&nbsp;A resealable container or freezer bag are both great options.<\/p>\n\n\n\n<p>If you know you&rsquo;ll finish the nuts within a couple of months, leaving them at room temperature is okay. Otherwise, it&rsquo;s better to refrigerate them.<\/p>\n\n\n\n<p>The gist of macadamia storage is to protect the nutmeat (or kernel) from the following:<\/p>\n\n\n\n<ul><li>moisture<\/li><li>excess air<\/li><li>sunlight<\/li><li>hot temperature<\/li><\/ul>\n\n\n\n<p>It might seem like a lot, but it&rsquo;s not that difficult.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"inshell-macadamia-nuts\">In-Shell Macadamia Nuts<\/h3>\n\n\n<p>If you buy in-shell macadamias, the shells protect the kernels from sunlight and excess air. That means you only need to ensure that unshelled macs sit away from moisture and in a cold place.<\/p>\n\n\n\n<p>A ventilated bag or a container without a lid in a pantry cupboard or on a shelf is usually good enough for that. Or you can transfer the nuts into a sealed bag or container and refrigerate if you need more time.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"shelled-macadamia-nuts\">Shelled Macadamia Nuts<\/h3>\n\n\n<p>For shelled macadamias, you need to keep them well sealed, and that&rsquo;s why an airtight container or plastic bag is a must. If the nuts aren&rsquo;t sealed, they get free access to air, which speeds up rancidification.<\/p>\n\n\n\n<p>If you decide to leave them at ambient temperature, find a spot that&rsquo;s cold and away from sunlight. For example, a pantry cupboard is typically a much better choice than leaving the macs on the counter.<\/p>\n\n\n\n<p>And if it&rsquo;s the middle of a hot summer and the temperature where you store your macadamias is much higher than 68&deg;F (20&deg;C), consider refrigeration. Otherwise, your macadamias might turn rancid within a month or two.<\/p>\n\n\n\n<p>When refrigerating macadamia nuts, make sure they&rsquo;re sealed tight. This prevents the nuts from absorbing any moisture and smells, and helps them retain quality for longer.<\/p>\n\n\n\n<p>Last, if you want to never bother about macs going rancid, you can freeze them. Let&rsquo;s talk about how.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><noscript><img decoding=\"async\" loading=\"lazy\" width=\"394\" height=\"600\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias.jpg\" alt=\"Nuts topped loaf of bread and a bowl of macadamia nuts\" class=\"wp-image-1770\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias.jpg 394w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias-197x300.jpg 197w\" sizes=\"(max-width: 394px) 100vw, 394px\"><\/noscript><img decoding=\"async\" loading=\"lazy\" width=\"394\" height=\"600\" src=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias.jpg.webp\" alt=\"Nuts topped loaf of bread and a bowl of macadamia nuts\" class=\"wp-image-1770 lazyload\" srcset=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias.jpg.webp 394w, https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias-197x300.jpg.webp 197w\" sizes=\"(max-width: 394px) 100vw, 394px\" data-pin-media=\"https:\/\/www.canitgobad.net\/wp-content\/uploads\/Nuts-topped-loaf-and-macadamias.jpg\" id=\"mv-trellis-img-5\" data-trellis-processed=\"1\"><figcaption>(credit: <a href=\"https:\/\/unsplash.com\/photos\/mepQiXCXETM\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Taylor Kiser (opens in a new tab)\">Taylor Kiser<\/a>)<\/figcaption><\/figure><\/div>\n\n<h2 class=\"wp-block-heading\" id=\"can-you-freeze-macadamia-nuts\">Can You Freeze Macadamia Nuts?<\/h2>\n\n\n<p><a href=\"https:\/\/www.ars.usda.gov\/ARSUserFiles\/oc\/np\/CommercialStorage\/CommercialStorage.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">You can successfully freeze macadamias for the long term<\/a>, and that&rsquo;s the recommended storage option if you want to prolong the shelf life of these nuts as much as you can.<\/p>\n\n\n\n<p>The procedure is as simple as it gets and takes only a minute or two to get done.<\/p>\n\n\n\n<p>Here&rsquo;s how to freeze macadamia nuts:<\/p>\n\n\n\n<ol><li><strong>Transfer macadamias to a freezer bag.<\/strong><\/li><li><strong>Squeeze out the air and seal the bag.<\/strong>&nbsp;Add a label with the name and date if you find that helpful.<\/li><li><strong>Put the bag in the freezer.<\/strong><\/li><\/ol>\n\n\n\n<p>That&rsquo;s all there is to it.<\/p>\n\n\n\n<p>(You can use the exact same process to freeze other nuts, including freezing <a href=\"https:\/\/www.canitgobad.net\/can-almonds-go-bad\/\">almonds<\/a> and <a href=\"https:\/\/www.canitgobad.net\/can-brazil-nuts-go-bad\/\">brazil nuts<\/a>.)<\/p>\n\n\n\n<p>Wondering how long you can freeze macadamias?<\/p>\n\n\n\n<p>Frozen nuts last for&nbsp;<a href=\"https:\/\/ucfoodsafety.ucdavis.edu\/sites\/g\/files\/dgvnsk7366\/files\/inline-files\/44384_0.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">more than two years<\/a>&nbsp;without much quality loss if they&rsquo;re sealed well.

They might also smell like old paint or putty, but the odor change isn&rsquo;t always easily discernible.<\/li><li>Shelled macadamia nuts last about 5 months at room temperature or a year in the fridge. Unshelled macs keep for a month or two longer if left at ambient temperature or more than a year if refrigerated.
