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 and toast them to a light brown in a 400°F (200°C) oven.
In a bowl, mix the grated cheese, salad oil, mustard, salt, cayenne, and beaten egg yolks until well combined.
Assemble and serve
Spread the mixture on the inside of the toasted biscuits.
Return the biscuits to the oven to heat through and 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 and add richness and a set, custard-like texture when heated.
- Cheese
- Adds savory flavor and salt, and browns on the surface when heated.
- Salad oil
- Adds fat that keeps the topping moist and spreadable.
- Stale rolls or biscuits
- Provide a dry, absorbent base that crisps when toasted and holds the topping.
The step that matters
Returning the biscuits to the oven. Heat that is too high or too long can overcook the egg yolks, making the topping dry or rubbery and browning the cheese too quickly. Heating just until warmed through keeps the topping soft and smooth.
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.
