๐งLower-salt version: nothing to cut. The salsa verde is already built without salt or capers, and the fish is now bought fresh. Taste and add lemon before any salt.
๐Buy fish and seafood fresh at the wet market, and freeze it at home if it is for later in the week. Frozen fish and prawns from the shop are often soaked in salt water or phosphate, which adds a lot of salt.
