Freeze chopped onions: You can then just pull out a bag of chopped onions and use them in recipes whenever they call for chopped onion. Doing them in bulk like this saves a lot of time and effort–and tears
Freezing Eggs - When you find a sale on eggs, you can freeze them to store for baking and cooking later. Eggs can not be frozen in the shell... but can be out of the shell. Crack a single egg into each slot in an ice cube tray. Freeze, then pop out and put back into the freezer in a zip lock bag freeing up your ice cube trays for other purposes. To use simply leave a cube per each egg the recipe calls for sitting at room temp in a bowl to defrost.
