Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Brain Cakes

Ingredients

Directions

Prepare the brains

  1. Wash the brains in salt and water, remove skin and fibers, and soak in salt water until needed.

  2. If cooking with the calf's head, tie the brains in muslin and boil for about 20 minutes.

  3. For separate cooking, place the brains in a stewpan, cover with water, and add salt, vinegar, onion, peppercorns, and bay leaf.

  4. Cook gently for about 20 minutes or until firm, then let cool.

Make the mixture

  1. Chop the cooked brains finely, season with salt and pepper, and mix in enough beaten egg to bind the ingredients.

  2. Stir the mixture over low heat until it thickens, then let cool.

Shape and fry

  1. Form the mixture into small round cakes, coat with beaten egg and breadcrumbs, and fry in hot fat until lightly browned.

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

What each ingredient does

Calf's brains
Form the main body of the cakes, giving a soft, delicate texture once cooked.
Eggs
Bind the chopped brains together and form a coating that helps the breadcrumbs stick.
Breadcrumbs
Form a crisp, golden outer crust when the cakes are fried.
Cooking fat
Conducts heat to brown the breadcrumb coating and cook the cakes through.

The step that matters

Stirring the mixture over low heat until it thickens. Over high heat the egg in the mixture can scramble and turn grainy, and the mixture can stick and scorch, so gentle heat keeps it smooth and cohesive enough to shape.

Swap the onion

How well each one fits the dish's main ingredients (egg, pepper, vinegar):

  1. Capsicumfits better
  2. Mustardfits better
  3. Cucumberfits better
  4. Onionthe original

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