Lemon Jelly Filling

This filling can be made up to 3 days ahead. Press plastic wrap directly onto the surface to prevent a skin from forming, then refrigerate. Stir gently before using to restore a spreadable consistency.

Store leftover filling in an airtight container in the refrigerator for up to 1 week. Once spread on cake, the filled cake should be refrigerated and consumed within 3 days. The filling may also be frozen for up to 2 months; thaw overnight in the refrigerator and stir before using.
