Why it works: Biscuit and mustard match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 121 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Deviled Biscuits
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Split the stale rolls or biscuits.
Toast them to a light brown in a 400°F (200°C) oven.
Make and bake
In a bowl, mix the grated cheese, salad oil, mustard, salt, cayenne, and beaten egg yolks until smooth.
Spread the mixture on the inside of the toasted biscuits.
Place the biscuits back in the oven to heat through.
Serve covered with a napkin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Bind the cheese mixture into a smooth, spreadable paste and add richness.
- Dry cheese
- Adds salty, savoury flavour and browns in the oven for a toasted topping.
- Salad oil
- Adds moisture and fat so the topping spreads smoothly and does not dry out.
- Stale rolls or biscuits
- Serve as the base; their dry crumb soaks up little moisture and holds the topping.
The step that matters
Toast the biscuits to a light brown before adding the topping. Toasting dries the crumb so it stays crisp under the moist cheese mixture instead of turning soggy. Stopping at light brown keeps the base from over-browning before the topping heats.
Swap the mustard
How well each one fits the dish's main ingredients (biscuit, cheese, egg):
- Mustardthe original
- Welsh onionfits about as well
- Asparagusfits about as well
- Spinachfits less well
Fit is the average pairing score against biscuit, cheese, egg. Candidates are from the same food group and used in at least 100 recipes.
