I save my lemon rinds when i make lemonade and let them freeze dry to use as zest.
Yesterday, I said, why not put a 1/2 dozen lemon rind halves in the fish pot while it heats up…
Turned out great. My 8yo daughter said “What did you DO to the fish daddy??”
Just a hint of lemon in the fish. My lemon rinds are not going to last long…
