Fish Fillets with Cucumber Raita

Make Ahead Tip: Cover and refrigerate the sauce (Step 1) for up to 2 days.

Notes:
Catfish: Look for U.S. farmed catfish--it's sustainably raised in non-polluting inland ponds and fed a mostly vegetarian diet.

Tilapia: U.S. farmed tilapia is the considered the best choice--it's raised in closed-farming systems that protect the surrounding environment. Central and South American tilapia is considered a good alternative. Avoid farmed tilapia from China and Taiwan--where the fish farming pollutes the surrounding environment.

Haddock (Scrod): To get the best choice for the environment, ask for U.S. Atlantic “hook-and-line-caught” haddock--this method causes the least damage to the sea floor and has the least by catch.
