I recently made lemonade, and rather than waste all that zest, I made compound butter. This butter is tasty and flavorful, perfect for toast or melted with seafood. You can refrigerate the butter into cool shapes, but I'm lazy so I keep it in a little cup. Bon Appétit has instructions for making a log:
- 1/2 stick butter
- 2 lemons, zested
- 1 tbsp rosemary, chopped
Soften the butter. Combine with zest and rosemary. Refrigerate.
