Better at room temp: Avocados

Perhaps the most irritating food in terms of ripening, avocados should be kept out of the fridge until they’re at their optimal freshness (which lasts, if you’ve ever bought one, about five minutes). Once they’re ripe, you can place them in the fridge for five to 10 days.

Tip: Keep the pit in the half of the avocado that you’re not going to eat; it keeps it fresher, longer.

Keep it cold: Nuts

This may come as a surprise, but your favourite healthy midday snack actually does better in the fridge. The oils in nuts can become rancid after a few months if they’re left at room temperature.

Fun fact: They can also be frozen, since they have such a small water content.

These are the foods you should never eat past the expiration date.

Better at room temp: Uncut Watermelon

Stop letting your huge watermelons hog all of the room in the fridge! This fruit is good left on the counter until it’s cut. Once you slice it, wrap it up and place it in the fridge for optimal freshness.

Keep it cold: Opened salami or pepperoni

Meats that you’ll typically find on a cheese board, like salami, cured ham, and pepperoni, should be put in the fridge once you open them. The cut end becomes seriously susceptible to bacteria growth if it’s left out on the counter or in the pantry.

You’re wasting your money if you throw out these underrated cuts of meat.

Keep it cold: Pure maple syrup

The real stuff has no preservatives and can become moldy after opening if it’s not chilled within a few weeks or months. But if you’re using commercial, processed maple syrup, it’s good to stay in the pantry. If you’re not looking forward to pancakes with cold maple syrup, pour out a serving size and pop it in the microwave for 30 seconds—it’ll take your flapjacks to the next level.

Keep it cold: Ripe bananas

Ripe bananas stay at their perfect peak for another week if you toss them in the refrigerator—but wait until they’re soft with plenty of spots. If you put still-green or not-quite-ripe bananas in the fridge, it’ll halt the ripening process and you’ll never get the perfect banana… unless you like ’em green (Tip: There is less sugar in them that way!).

Here’s why you should never throw out banana strings.

Better at room temp: Garlic

Entire bulbs of garlic can be left on the counter for up to three to four months, while individual cloves will last up to 10 days. And if you’re afraid you won’t use it quickly enough, you can store whole, unpeeled garlic in the freezer and remove cloves as you need them. But who doesn’t use garlic quickly?

These kitchen mistakes could be ruining your food.

Better at room temp: Potatoes

Moisture makes spuds go blah; store in the pantry or on the counter for up to three weeks. Once you see ’em start to grow sprouts or get soft, that’s a sign to use them quickly (especially in soups and stews!) or ditch them. Also, beware: Potatoes exude (non-scented) fumes when they’re sitting out that can spoil other foods like onions more quickly.

Try this simple trick to keep potatoes from turning brown.

Keep it cold: Natural peanut butter

The oils in natural peanut butter can go rancid quickly when stored at warm temperatures. Take your PB out of the fridge 15-20 minutes before use and gift it a good stir to soften it up. Commercial, processed peanut butters, which include more than just peanuts as an ingredient, can be left in the pantry for up to a year, since there are added preservatives in the mix.

Here’s why you should never wrap your leftovers in foil.

Better at room temp: Hot sauce

Acidic, vinegar-based foods like this fiery condiment are fine at room temperature. However, you can refrigerate it for longer-lasting flavour, just make sure to bring it to room temp before use.

Here are the grilling mistakes that could make you sick.

Better at room temp: Bread

Nothing makes loaves go stale faster than a stint in the refrigerator. Freeze what you won’t eat within a few days. Now that eating bread is less popular in North American diets, we recommend popping your loaf in the freezer right when you get home from the supermarket. That way, you don’t even have to worry about keeping an eye on it for mould.

Avoid these common mistakes when it comes to buying bread.

Keep it cold: Coconut oil

All oils can become rancid after a few months on the counter, especially the oils that are used less frequently (enter: coconut oil). Coconut oil is a solid fat whether it’s in the pantry or in the fridge, so all you need to do is pop it in the microwave for a few seconds to bring it to its liquid state.

Better at room temp: Cake

Chilled air dries it out, no matter how well wrapped it is; unless frosting is literally melting off, store cake on the counter. However, if your kitchen is hot and humid, the cake can spoil quickly, so refrigeration isn’t the worst option.

Better at room temp: Tomatoes

Avoid the fridge at all costs: Tomatoes will turn mushy and bland in there. They’re best left out of zip-locked bags and instead placed in a paper bag until they’re ripe. Once ripened, you can keep ’em out on the counter.

Here are the other foods you’ve been spoiling by putting them in the fridge.

Keep it cold: Butter


While butter is on the USDA’s safe-to-eat unrefrigerated list of foods, it’ll last a whole lot longer in the fridge. If you have a hot or humid kitchen, your butter could spoil within a few days, so it’s best kept chilled.
