Fresh lemon juice can be frozen in either glass or plastic containers, but plastic is generally preferred due to its flexibility and reduced risk of breakage.
When freezing lemon juice, the primary concern is expansion. Liquids expand when they freeze, and this expansion can cause containers to crack or break.
Plastic Containers: Plastic containers, especially those designed for freezing, are flexible and can accommodate the expansion of the lemon juice. Choose food-grade plastic containers or freezer bags. Ensure they are properly sealed to prevent freezer burn and leaks.
Glass Containers: Glass containers can be used, but it's crucial to leave ample headspace (about an inch or two) at the top of the container to allow for expansion. Tempered glass is more resistant to cracking than regular glass. Avoid using thin or delicate glass containers. It's also best to freeze the juice in smaller portions to minimize the risk of breakage.
Ultimately, both glass and plastic can work, but plastic offers a safer and more convenient option for freezing lemon juice.
Freeze lemon juice in ice cube trays for convenient, pre-portioned amounts. Once frozen, transfer the cubes to a freezer bag for longer storage. This makes it easy to add a splash of lemon juice to recipes without thawing a large quantity.
