Ingredients in homemade lime curd usually include:
- Fresh lime juice
- Eggs
- Sugar
- Butter
Store-bought versions may contain additional preservatives and stabilizers to increase shelf life and maintain consistency.
Texture and flavor can vary between homemade and store-bought lime curds. Homemade versions often have a fresher, more vibrant taste, while store-bought curds may have a more consistent texture.
Storage recommendations:
- Homemade: Store in an airtight container in the refrigerator
- Store-bought: Follow package instructions, typically refrigerate after opening
For longer storage, both types can be frozen for up to 3 months. Thaw in the refrigerator before use.
When properly canned, homemade lime curd can last 3-4 months at room temperature. Store-bought canned versions may have an even longer shelf life due to commercial processing methods.
Extending the Shelf Life: Freezing Tips
Freezing lime curd can significantly extend its shelf life beyond typical refrigeration times. When properly frozen, lime curd can last up to 6 months while maintaining its quality and flavor.
To freeze lime curd, transfer it to airtight, freezer-safe containers. Leave about 1/2 inch of headspace to allow for expansion during freezing. Alternatively, use ice cube trays for portioned servings.
Label containers with the freezing date to track storage time. Place containers in the coldest part of the freezer, typically toward the back, for optimal preservation.
When ready to use, thaw frozen lime curd in the refrigerator overnight. Avoid thawing at room temperature, as this can promote bacterial growth and affect texture.
