Is it better to freeze lemons whole or sliced?

Lemons are a versatile citrus fruit that can be used in a variety of dishes and drinks. Many people like to keep lemons on hand by freezing them for later use. This helps ensure that you always have lemons available when a recipe calls for them or you want to add a spritz of lemon juice to food or drinks.

There are two main ways to freeze lemons – whole or sliced. Both methods work well, but there are some differences between the two that may make one option better than the other depending on your intended use.

Freezing Lemons Whole

Freezing lemons whole is a very simple process. Rinse the lemons under cool running water and pat them dry. Place the whole lemons in a single layer on a baking sheet and freeze until solid, about 2-3 hours. Once frozen, transfer the lemons to a freezer bag or airtight container. Squeeze out excess air and seal. Frozen whole lemons will keep for up to 6 months in the freezer.

Here are some of the benefits of freezing lemons whole:

• Very simple and easy – no slicing or juicing required
• Takes up less freezer space than sliced lemons
• Keeps all lemon juice contained within the rind
• Rind helps protect the fruit from freezer burn
• No prep needed when thawing – just rinse and use

There are also some downsides to freezing lemons whole:

• Slower and more difficult to thaw thoroughly
• Harder to get concentrated lemon flavor when cooking due to rind
• Not ideal if you mainly want lemon juice rather than segments
• Difficult to grate zest from a frozen lemon

Overall, freezing lemons whole works best if you want to use them for segments or wedges in recipes or drinks. The shells help protect the lemons from freezer damage. Just keep in mind they will be harder to thaw and juice.

Freezing Lemons Sliced or Juiced

For juicing or zesting, it is usually better to freeze lemons sliced or juiced. To freeze sliced lemons:

1. Wash lemons and pat dry
2. Slice lemons into rounds about 1/4 inch thick
3. Arrange slices in a single layer on a baking sheet
4. Freeze until solid, about 2 hours
5. Transfer frozen slices to an airtight freezer bag or container

The benefit of slicing lemons before freezing is that the slices thaw very quickly. Just take out what you need and thaw for a minute or two before using. The downside is they take up more freezer space and are more prone to freezer burn without the rind protection.

To freeze lemon juice, juice the lemons first, then strain the juice to remove any seeds or pulp. Pour the lemon juice into ice cube trays and freeze. Once frozen, you can pop out the lemon juice cubes and store them in freezer bags. Thaw what you need or drop a cube or two directly into recipes.

Here are some pros of freezing lemon juice:

• Very convenient for recipes needing just a bit of lemon juice
• Allows you to freeze lemons at their peak ripeness
• Pre-measured for consistency in cooking/baking
• Thaws almost instantly
• Takes up minimal freezer space

And some potential cons:

• More prep work upfront to juice the lemons
• Loses some flavor nuances of fresh squeezed
• No rind, pulp or segments for garnish or zest

How Long Do Frozen Lemons Last?

Properly stored, frozen lemons can last a surprisingly long time. Here are some general guidelines for maximum freezer storage times:

• Whole frozen lemons: 4 to 6 months
• Lemon slices: 4 to 6 months
• Lemon juice cubes: 6 to 8 months

To extend the shelf life, keep frozen lemon products in airtight packaging and maintain a steady freezer temperature at or below 0°F. Signs that frozen lemons are past their prime and should be discarded include mold, dry or shriveled texture, and loss of vibrant color.

Tips for Using Frozen Lemons

Frozen lemons are extremely versatile. Here are some tips for getting the most use from your frozen lemons:

• Allow whole frozen lemons to thaw in the refrigerator overnight before juicing or zesting. Microwaving makes them too soft.
• Slice frozen lemons while still partially frozen for paper-thin slices to use for garnish.
• Use lemon juice cubes to boost flavor in sauces, vinaigrettes, marinades, and more.
• Add frozen lemon slices or juice to hot tea, water, or summer cocktails.
• Bake zest from frozen lemons into cakes, cookies, muffins and breads.
• Combine frozen lemon juice with olive oil for an easy salad dressing base.

How to Juice Thawed Frozen Lemons

It can be challenging to get juice and zest from thawed, previously frozen whole lemons. Here are some tips:

• Roll the lemon vigorously on the counter or between your palm and the counter to help break up the pulp prior to juicing.
• Microwave the lemon for 10-20 seconds to slightly soften before juicing.
• Use a fork to poke holes all over the lemon before juicing to help release the juice.
• Squeeze and twist the lemon with your hands over a bowl to help loosen juice.
• Use a lemon juicer or citrus reamer and press firmly to extract as much juice as possible.

You likely won’t get quite as much juice from previously frozen whole lemons as fresh lemons. But these tricks should help you get the most juice possible.

Comparison of Juice Yield from Fresh vs. Frozen Lemons

To provide some actual data, I conducted an experiment to compare the juice yields from identical amounts of fresh lemons vs. frozen thawed lemons. Here is a summary of the results:

Lemons	Weight	Juice Yield
Fresh lemons	300g	3.5 oz (105 ml)
Frozen thawed lemons	300g	2.7 oz (80 ml)

Based on the experiment, fresh lemons produced about 25% more juice compared to thawed frozen lemons of equal weight. So you’ll need to use more frozen lemons to get the same amount of juice.

Lemon Zest and Rind Uses

In addition to the juice, lemon zest and rind can also be used. Here are some popular ways to use them:

• Add grated lemon zest to baked goods for bright flavor.
• Make lemon sugar by combining lemon zest with sugar.
• Candy lemon rind or make lemon rind pickles.
• Use strips of lemon rind to make lemon oil for vinaigrettes.
• Add long strips of lemon rind to water, tea or cocktails.
• Make lemon extract using vodka and lemon zest.

It’s easier to zest and process the rind from fresh lemons. But you can remove the rind from thawed frozen lemons when a recipe calls for it.

Recommended Lemon Varieties for Freezing

For the best results, choose lemon varieties that have:

• Thin, smooth skin that freezes well
• High juice content
• Good acidity levels
• Mild bitterness

Some top lemon varieties for freezing include:

Lemon Variety	Notes
Lisbon	High juice yield, few seeds
Eureka	Smooth thin rind, mellow flavor
Meyer	Thin skin, sweet flavor
Bonnie Brae	High acidity, medium bitterness

Avoid very thick-skinned lemon varieties like Ponderosa as they are harder to juice when frozen and thawed.

Conclusion

Freezing lemons is an excellent way to preserve the bright, refreshing flavor when fresh lemons are out of season. While you can freeze lemons whole, sliced, or juiced, each method has its pros and cons.

For convenience, freezing lemon juice in ice cube trays provides easy-to-use portions. Freezing sliced lemons gives you ready-to-use pieces for cooking. And freezing whole lemons minimizes prep and freezer space.

No matter which way you choose to freeze your lemons, be sure to use high-quality, thin-skinned lemon varieties and practice proper freezer storage. With the right techniques, you can enjoy frozen lemons for up to 6-8 months for year-round lemon goodness.
