1. Make stale cereal, crackers, chips, and popcorn edible again by toasting in the oven.
Spread stale snacks in a single layer on a baking sheet and pop them in a 350-degree oven for 3-5 minutes.
2. Condition wood surfaces with expired mayo.
The oil in mayonnaise helps moisturize solid wood tabletops to restore moisture and even remove water stains.
3. Make finger paint with expired Greek yogurt.
Mix yogurt with food coloring or even Kool-Aid mix and let kids paint on a white, plastic tablecloth. As long as the yogurt isn’t too far gone (no more than 3 weeks past expiration) you can still eat it.
4. Or, use expired Greek yogurt as an exfoliating face mask.
Greek yogurt is packed with lactic acid, a common ingredient in beauty products. Use your slightly expired yogurt as a face mask by mixing two tablespoons of Greek yogurt with one tablespoon of honey (a natural moisturizer). Apply the cream to your face and leave it on for 15 minutes before washing off with a warm water.
5. Exfoliate your hands, face, and body with stale coffee grounds.
Add grounds to facial or body scrubs, and enjoy smoother skin!
6. Use sour milk to make cakes, biscuits, waffles, and pancakes.
Sour milk is a great substitute for buttermilk and tastes great in baked goods.
7. Disinfect your kitchen with dry white wine.
The alcohol, combined with the acidity, helps remove stains and kill germs.
Warning: the acidity can damage some countertops like granite.
8. Trap fruit flies with stale red wine.
Leave a bit of red wine at the bottom of the bottle and let it sit out. The flies will flock to the sugary liquid and get trapped inside. You can also put the red wine in a separate container, cover it with plastic wrap, and poke holes in the top so flies can get in, but not out.
9. Replant a stump of stale celery.
So many times have I only used a stalk or two of celery. Instead of tossing any leftover celery that’s gone stale, use the base to grow more!
Stand the base in a small dish of water for a week or so until new leaves appear in the center. The leaves will be yellow at first, but they’ll turn green eventually. When that happens, plant the celery in the ground or in a pot with soil.
Celery is just one vegetable you can regrow from scraps. Check out some others in 7 Vegetables You Should Never Pay For.
10. Sauté wilted or slightly brown lettuce.
It’s common to sauté most greens, why not lettuce? Just don’t eat rotten lettuce that’s been sitting in brown juices.
11. Keep a bag of wilted herbs and vegetables scraps in your freezer for making stock later on.
Don’t toss those wilted herbs and vegetables in the trash! Freeze them for later and make homemade vegetable broth.
12. Paint with spices that have lost their potency.
Some spices will lose their flavor over time. Whole spices tend to stay fresh for about 4 years, ground spices for about 3 years, and dried leafy herbs for only about 1-3 years.
If you have ground spices like nutmeg, paprika, cinnamon, and other colorful seasonings that have been sitting in your spice rack for years, turn them into paint! Just add a teaspoon or so of hot water and let kids paint away — they’ll love the smell!
13. Soften brown sugar clumps in a blender.
Stick hardened brown sugar into a blender and pulse until useable. Depending on how hard the chunks are, you may need to add a few drops of water to help break up the clumps.
14. Turn stale bread into bread crumbs.
If your bread is still slightly soft, slice it into 1/2-inch cubes and bake in a 300-degree oven until all the moisture is gone. Then, fill your blender up to a third of the way with dried cubes, and blend to desired texture. Store crumbs in the freezer.
15. Or, microwave stale bread for 20 seconds to make it edible again.
If you have stale bagels or breads that are too chewy to enjoy, wrap pieces in a moist paper towel and microwave. The moisture will soak into the bread.
16. Empty expired canned goods and recycle the can.
