Master chef shares 14+ tips to keep food fresh for longer

1. Make sure your fridge is at the correct temperature
You want to make sure your fridge is cold enough to keep food fresh without freezing it. The recommended temperature is 38-40°F. For increased accuracy, get a fridge thermometer.

2. Roast tomatoes
Have you noticed your tomatoes starting to wrinkle? Get an extra week with tomatoes by roasting tomatoes and storing in a container filled with olive oil. Refrigerate.

3. Add butter to cheese
Rub the cut edges of your cheese with butter. This keeps hard cheese from drying out.

4. Avocados
Keep your avocados on the counter until ripe. This usually takes two or three days, depending on their state when you bought them. When they soften a bit, store them in the fridge to keep them from going bad. If you are storing half an avocado, make sure to wrap in an airtight bag before putting in fridge.

5. Keep herbs fresh with a jar and water
This is a trick many restaurants use and it is very simple. Snip about half an inch off the ends of the herbs to freshen up any dried ends and place them in a glass, vase, or even mason jar filled about halfway with cool water. Then cover the leafy part of the herbs with a resealable bag. Don’t use plastic wrap, as it will squeeze the herbs too tightly together. But as the water will continue to feed the herbs and keep them fresh, the plastic bag will keep air from getting to them, which can dry them out and cause them to wilt.

6. Get long-lasting berries
Prevent berries from getting moldy and soft. Mix one part of vinegar with ten parts of water. Rinse your berries in this solution before putting in the fridge. This method will allow your berries to last at least 1 week longer.
7. Wrap lettuce with a damp paper towel
Before putting in fridge, wrap lettuce with a damp paper towel. If you see leaves wilting, try to revive it by soaking the lettuce in ice water for a few minutes.
8. Store onions in pantyhose
Onions can stay fresh for up to 6 months if properly stored in a cool, dark place. Buy some clean pantyhose, and place whole onions into the feet. Tie a knot with the pantyhose between each whole onion. Repeat until you fill the entire pantyhose. Hang up in a closet, pantry, or kitchen wall. (Yes, this can be decor!)
10. Store cucumbers in sealable container
Cut your cucumbers into about 1/4-inch slices. Stack the slices in a sealable container. Then, place a folded paper towel on top of your cucumbers and put a lid on your container. Store your cucumbers upside down (so that the paper towel is on the bottom). The towel will soak up extra moisture.
11. Keep guacamole fresh with water
Put guacamole in an airtight container and add some water at the top before sealing and leaving in fridge. This might sound strange but the water acts as a protective shield against oxygen. You can keep the guacamole in the fridge for 3 days. Once you are ready to eat it, take the guacamole out, dump out the water, and mix it up before serving.
