We had no idea you could freeze eggs. And freezing ripe avocados seems obvious, but we hadn’t tried it until we read through these tips from registered dietitian, Kajsa Ernestam that coudn’t be more relevant now.

Learn to save those precious perishables both to reduce waste and to reduce those grocery store runs right now. Which one of Kajsa’s hacks have you not tried?

How To Make Your Perishables Last Longer

Milk | If your milk’s sell-by date is approaching, leave a little room in the container for expansion and put it in the freezer. The dairy industry says milk can be stored frozen up to 3 months, but it’s best if you use it within the first month of freezing. Half & half can also be stored in the freezer but only for 3 months.

Eggs | Eggs can be stored for over a month in the freezer, but you have to remove them from the shells first. You can freeze a mix of the whipped eggs, or the whites and yolks separately.

Greek Yogurt | Freezing greek yogurt will extend its shelf life by several months. Even though freezing it does have an effect on the texture, eating thawed greek yogurt is just as good for you as eating it straight away. TCM tip: Texture’s not an issue if you add yogurt to a sauce. Try this one! 

Avocado | Ripe avocado can be stored frozen for 4 to 6 months. You can either cut an avocado in half and freeze the two halves or peel and mash it up and put a mix in a freezer. Add lemon juice and seal the avocado tightly in plastic to minimize browning.

Onions | Onions are best to be frozen chopped or raw as most dishes use onions with little to no thawing. Because chopped onions tend to freeze in clumps, bang the bag against the counter a few times before each use. Use your frozen chopped onions within 3 to 6 months for the best retention of flavor.

Cheese | Avoid freezing cheese in large blocks as it will then lose moisture. Shredding or slicing cheese is the best way to preserve it in the freezer. Add a little cornstarch or flour to a bag of shredded cheese and shake it to make sure it doesn’t clump in the freezer.

Bread | A fresh loaf of bread can be preserved from molding or drying out in the freezer. Put it in the oven to thaw and serve it hot. TCM tip: You want bread recipes? We got bread recipes Try these. 

Potato Chips | Freezing potato chips will preserve them from becoming stale. Since most of the moisture is already cooked out of potato chips, you can freeze them to help prolong their shelf life without the risk of them getting soggy. When you’re craving a salty snack, grab a few and go.

Leftovers | Warm food should always be cooled down before being put in the fridge or freezer. As a general rule of thumb, uncooked and some cooked food can be put in a freezer at any point and kept there for about 3 months.

Note: It is a myth that foods with a freezer burn are bad for your health. Freezer burn does cause a bad color and flavor, and can affect the texture of the food a lot of the time — but it’s not harmful for the consumption.
