Breaded Fish Sandwiches with Mint-Caper Tartar Sauce

Breaded Fish Sandwiches with Mint-Caper Tartar Sauce

Spiking tartar sauce with mint and capers improves the classic fish sandwich deliciously. Cutting the fish into a square shape helps it fit the bun better. Be sure to use a sweet onion, and soak it in ice water so that you get the crunch but no harsh bite.

1. Preheat oven to 350°.
