Ingredients

Directions

Prepare

  1. Wash and drain the brook trout in a colander for a few minutes.

  3. Sprinkle the trout with coarse sea salt.

Cook and serve

  1. Place the trout in a buttered pan that is hot but not burning.

  2. Add a little salt to prevent sticking.

  3. Do not turn the trout until browned enough for serving.

  4. Add butter.

  5. Serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Brook trout
Forms the main body of the dish, cooking through as its flesh firms and turns opaque.
Flour
Coats the fish so the surface browns and forms a crisp, golden crust.
Butter
Conducts heat into the pan and adds richness and browning flavour to the fish.

The step that matters

Do not turn the trout until browned enough for serving. Fish sticks when turned too early because the proteins have not yet formed a crust that releases from the pan. Waiting until the surface is well browned lets it lift off cleanly and keeps the skin and flesh intact.
