Why it works: Mustard and onion match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

  2. Toast the slices slowly until golden brown.

Season and top

  1. Mix butter with dry mustard, paprika, and onion juice.

  2. Spread the mixture on the toasted bread.

  3. Sprinkle with grated cheese.

Bake

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

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

What each ingredient does

Bread
Provides the crisp, toasted base that holds the spread.
Butter
Carries the seasonings and adds richness and moisture to the spread.
Dry mustard
Adds sharp, pungent flavour that cuts the richness of the butter and cheese.
Grated cheese
Melts and browns in the oven, adding savoury flavour and a golden top.
Paprika
Adds mild warmth and colour to the spread.

The step that matters

Toast the slices slowly until golden brown. Slow toasting dries the bread evenly through its thickness, producing a crisp base. Fast, high heat can scorch the surface while leaving the centre soft, so the spread sits on an uneven base.

Swap the onion

How well each one fits the dish's main ingredients (wheat, butter, mustard, cheese):

  1. Lettucefits better
  2. Potatofits better
  3. Chivefits better
  4. Onionthe original

Fit is the average pairing score against wheat, butter, mustard, cheese. Candidates are from the same food group and used in at least 100 recipes.
