Why it works: Lemon and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,973 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Potato Puff

Ingredients

Directions

Prepare

  1. Beat the butter with a fork until it creams.

  2. Mix the potatoes with the creamed butter.

  3. Whip the egg yolks well with the milk.

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

What each ingredient does

Eggs
Egg yolks enrich and bind the mixture, while whipped whites lighten it and help it rise.
Potatoes
Mashed potatoes form the body of the puff and give it a soft, tender texture.
Butter (in the method)
Creamed butter adds richness and moisture to the mashed potato base.
Milk
Milk adds moisture and softness to the mixture, helping it set tender when baked.

The step that matters

Beat the egg whites to a stiff froth and add them last. Whipped egg whites trap air that expands in the oven and lifts the puff. Folding them in gently at the end, rather than beating them into the base, keeps that air from collapsing.

Swap the onion

How well each one fits the dish's main ingredients (potato, milk, mustard, lemon, nutmeg, thyme, egg):

  4. Onionthe original

Fit is the average pairing score against potato, milk, mustard, lemon, nutmeg, thyme, egg. Candidates are from the same food group and used in at least 100 recipes.
