The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Add structure and richness to the batter as they set during baking.
Yeast
Produces gas during rising, leavening the batter so it becomes light.
Butter
Adds fat for a tender crumb and rich flavour.
Flour
Forms the gluten and starch network that gives the bun its structure.
New milk
Provides moisture and proteins that help browning and a soft crumb.

The step that matters

Gradually add flour until the batter is similar to pound cake. Too much flour makes the batter stiff and dense, limiting the rise. Adding it gradually lets you stop at a pourable, cake-like consistency that yeast can lift.

Swap the potato

The recipe marks potato as optional. How well each one fits the dish's main ingredients (milk, butter, egg, flour):

  1. Chivefits about as well
  2. Potatothe original
  3. Leekfits about as well
  4. Asparagusfits about as well

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