Buying food in bulk does not apply if deliveries do not hold. But don't worry – if you're smart about it, you can get the cooking supplies to last longer.
Eat older foods first
Practice the first in the first out rule. When you get home from the grocery store and unload items in the fridge, place them on the back of the fridge, not in advance. Reserve the front spaces for older items that are closer to expire. Hopefully this will make you remember to use the food before it goes bad, which will prevent you from wasting food and money.
Focus on low-calorie cheap foods
Every dollar counts, so when you get the chance to buy food, focus on healthy but cheap staples that provide high nutritional value. Some great pillars that can both last a long time and provide good health support are brown rice, quinoa, dried beans, oats, sweet potatoes and sunflower seeds.
 Preserve with lemon juice
If you cut a large amount of fruit at once to store as a snack for later, consider sprinkling it with a little lemon juice. This will prevent fruit, like an apple, from browning.
Flip Containers Over
We've all been there: we've all made pasta and then got a half-use jar of sauce from the fridge to discover that it was almost impossible to get the sauce out of the jar. To prevent this, try to keep the jar upside down. This can also be helpful for things like salsa. It will also keep mold away.
Before turning a can upside down, however, you must make sure that the lid is properly seated or else you may encounter unlucky movement the next day. You may even want to consider adding some aluminum foil to the lid or putting a napkin under the jar if you think it is prone to leak.
If you buy a large amount of something, like a pack of 10 chicken breasts, you can only take out what you need for the next few days and then freeze the rest. The night before you want to make chicken again, you just take what you need out of the freezer. This will extend the number of days the food is good for and will prevent you from wasting large amounts of food.
Keep cheese covered
Leave the wrapper on a block of cheese as you cut it. Place the part of the block you are not using, with the cover still on it, in an airtight bag and back in the fridge. Leaving the plastic on the cheese block when you cut it will prevent you from touching the cheese and spreading bacteria from your hands to the food. By not stirring it the cheese will last longer.
Leave in Avocado Pits
Guacamole can be a delicious side or snack but it can also destroy quickly. If you make a large batch of guacamole, or have it served at a later date, add a few pits in the bowl with the guacamole. This will prevent it from dazzling.
If you have half an avocado left, make sure it's half the pit. Place the saran wrapper before storing it in the fridge.
If you are only going through small quantities of flour at a time, you may want to consider storing it in the freezer. Doing so will reduce the risk of bugs entering the container.
Wrap Banana Tops in Cloth
There is a reason you see bananas sold in clusters. A single web will turn brown faster than if it is held in a bunch. To make them last even longer, insert the tops with glue.
Difference Between Sell By and Use By Date
Expiration dates are meant to help you understand when food is the freshest. USDA Food Safety and Inspection Service FoodKeeper app helps you understand how long food is good for.
Many articles are still believed to be safe to eat even after they have technically expired. However, do some research on the specific foods. Examine the food for mold and make sure it does not emit an odor that it should not. If in doubt, go with the safer option and through the food away.
Store Onions in Tights
Do you have any tights that you regret buying? It may be another use for them. Try to put onions in old tights, tie a knot between each onion and hang them in a dark cupboard. Some foods report this method and keep onions fresh for up to eight months.
