Can You Freeze Lemons?
Yes, you can freeze lemons in various forms for up to 4 months. Whole lemons, slices, juice, and zest all freeze well. Frozen whole lemons are easier to zest, and frozen juice cubes provide convenient portions for cooking and drinks.
Key Takeaways
- Freezing lemons is an excellent way to preserve them when you have more than you can use or find a good sale.
- Thawed whole lemons yield more juice than fresh lemons because freezing breaks down cell walls.
- Lemon wedges and slices become soft after thawing but work well as drink garnishes while still partially frozen.
Explanation
Freezing lemons is an excellent way to preserve them when you have more than you can use or find a good sale. All parts of the lemon freeze successfully, though each has optimal storage methods and uses.
Whole lemons can be frozen as-is in freezer bags. Once thawed, they become soft and are best for juicing. A useful trick: frozen whole lemons are actually easier to zest than fresh ones. Grate the zest while frozen before thawing to juice.
For maximum convenience, freeze lemon juice in ice cube trays. Each standard ice cube is about 2 tablespoons. Zest can be frozen separately in small containers or mixed with a little juice. Lemon slices frozen on a tray then bagged work well for drinks, similar to frozen grapes as drink chillers.
Lemons contain approximately 53mg of vitamin C per fruit (about 59% of the daily value), and this vitamin is moderately heat-sensitive but stable at freezing temperatures. Frozen lemon juice retains roughly 85-90% of its vitamin C content after 4 months at 0°F (-18°C), compared to fresh lemon juice which loses about 20% of its vitamin C within just one week of refrigeration in an opened container. Freezing lemon juice is therefore one of the most effective ways to preserve both its flavor and nutritional value.
The zest of a lemon contains limonene and other aromatic oils concentrated in the yellow outer peel. These oils are more potent when the lemon is frozen because cold temperatures make the peel firm and easier to grate finely without digging into the bitter white pith beneath. One medium lemon yields about 1 tablespoon of zest, and freezing a dozen lemons worth of zest in a small container provides months of ready-to-use citrus flavor for baking, dressings, and finishing dishes. Meyer lemons, which are sweeter and less acidic than standard Eureka lemons, freeze particularly well and add a floral note to dishes.
Things to Know
- Thawed whole lemons yield more juice than fresh lemons because freezing breaks down cell walls.
- Lemon wedges and slices become soft after thawing but work well as drink garnishes while still partially frozen.
- The same methods work for limes, oranges, and other citrus fruits. Frozen avocado also pairs well with lemon juice.
