Helpful Lesson 1: 10 Tips for Keeping Produce Fresh Until Your Next Trip to the Grocery Store

First, plan your menu for the week with some attention to what foods will last longer. The end of the week's menu should make use of pantry items and hearty vegetables like cabbage and potatoes.

Here are the 10 tips from Caroline Lange of Bon Appetit to keep produce fresh until our next trip. (By the way, I've done almost everything incorrectly all this time!)

1. Store your produce DRY.

A little humidity is a good thing for produce—but wet is bad news. Some moisture will keep produce perky; too much moisture can promote mold or mushiness. Make sure you thoroughly dry anything you’re washing before putting it away. There are a few exceptions to this rule: Scallions like to be stored upright, roots-down, in water at room temp—and they’ll keep growing that way forever as long as you freshen the water every now and then. Asparagus is more like a bouquet of fresh flowers: Trim the ends, set in a glass of water, and refrigerate until ready to use. Storing whole carrots in a covered container of water will keep them firm; same for halved stalks of celery. Change the water every two or three days.

2. When in doubt, bag it.

A plastic bag will help prevent the moisture in your vegetable from evaporating, which means it won't go limp after a few days. It works for hardy greens, too: Remove the thick stems, then tuck into a plastic bag or reusable lidded container.

3. Swaddle your herbs.

Start by removing any twist-ties or rubber bands from your herb bunch. If your herbs are very dirty, wash them first (otherwise, consider washing as you use them so as to introduce as little extra moisture as possible). To dry, use a salad spinner or roll up between two layers of clean, dry dish towels. Gently bundle the herbs in a dry paper towel. Place the bundled herbs in a resealable plastic bag (you can put multiple bundles of herbs in the same bag) or a plastic container.

4. Isolate "gassy" produce.

Some fruits and vegetables—like apples, ripe bananas, pears, and potatoes—produce a gas called ethylene that accelerates the ripening process of other fruits and vegetables. For this reason, if you want to ripen something quickly, stash it with your apples. If you’re trying to prolong lifespans, keep everybody as separate as you can. Let bananas have their own spot. Don’t store potatoes and onions together, and keep apples in a designated part of the fridge.

5. Transfer ripe fruit to the fridge.

Some fruit you want to keep out at room temperature so that it can ripen—avocados, pineapple, mango. Once it’s ripe, though, move it right over to the fridge, where you can essentially pause the ripening process. This is a short-term solution—everything will go bad eventually—but it’ll buy you 2 or 3 extra days with that perfectly ripe avocado.

6. Freeze!

Let fruit reach the desired stage of ripeness, then peel and cut into pieces if necessary and freeze in a single layer on a parchment-lined sheet tray until solid. Break up the frozen pieces and store in a resealable plastic bag or freezer-safe container for up to 3 months. You’ll want to chop and blanch most vegetables before freezing (and remember, not everything freezes well).

7. Keep citrus and ginger in the fridge.

You know how every stock photo of a kitchen has a bowl of lemons out on the counter? Looks nice, that’s for sure, but those lemons aren’t gonna last. Citrus will be happy (firm, juicy, not shriveled) for ages longer if you keep it in the fridge. Same for ginger (and fresh turmeric root).

8. The softer it is, the sooner you should use it.

Make an action plan based on which produce has the shortest life. Prioritize lettuces, spinach, and other soft greens; cucumbers; peppers; cherry tomatoes; broccoli and cauliflower. Save your potatoes and sweet potatoes, cabbage, carrots, fennel, and even hardy greens like kale and collards for the last days before you head back to the grocery store. Related: If your produce has leafy tops (like beets or carrots), remove them from the vegetable and, if you want to eat them, store them separately.

9. Learn the coldest parts of your fridge.

Generally, the top few inches of the fridge are prone to temperature swings (i.e., accidental freezing). Keep your most delicate produce (like herbs and lettuces) away from that top section and in the middle of the fridge.

10. Give everybody some breathing room.

If you’re only going to the grocery store once per week, it follows that your fridge is going to be pretty full. Try your best not to cram your crisper drawers. That space allows the fridge to work more efficiently: With air circulating around the produce, moisture evaporates and mold is held at bay. You’ll also be able to better see and use what you have.
