Baked Brains

Oven, in the book's wordsA hot oven

Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the brains

  1. Soak the calves' brains in cold salted water for 2-3 hours until blanched.

  2. Remove the outer skin and drop the brains into slightly salted boiling water with the onion slice; boil for 10 minutes.

Coat and bake

  1. Roll the brains in melted butter, then in very fine cracker crumbs, and season with salt and pepper.

  2. Place each brain on a large slice of bacon in a baking pan.

  3. Bake in a hot oven at 400°F (200°C) for 30 minutes.

Serve

  1. Serve with sour sauce and sliced lemon.

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

What each ingredient does

Calves' brains
The main protein, which firms and sets into a tender, delicate texture when cooked.
Melted butter
Carries the cracker crumbs and adds richness and browning to the outside.
Very fine cracker crumbs
Form a crisp, golden coating that helps the brains hold their shape while baking.
Large slices of bacon
Lay under each brain, adding fat and savoury flavour as they cook.

The step that matters

Blanching the brains in cold salted water. Soaking draws out blood and impurities, leaving the brains paler and milder in flavour. Skipping or shortening this step can leave a stronger, greyer result.

Swap the onion

How well each one fits the dish's main ingredients (butter, pepper, sauce, lemon):

  1. Capsicumfits better
  2. Shallotfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against butter, pepper, sauce, lemon. Candidates are from the same food group and used in at least 100 recipes.
