Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Melt the butter in the milk over medium heat until it boils.
Add the flour and mix well until combined.
Let the mixture cool, then mix in the eggs, sugar, and lemon peel.
Bake
Bake in a preheated oven at 350°F (175°C) until golden.

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
- Provide structure as they set, and steam from them helps the puffs rise.
- Butter
- Adds richness and fat, tenderizing the dough and aiding browning.
- All-purpose flour
- Starch and gluten form the batter's structure that holds the puffs.
- Milk
- Supplies liquid moisture that turns to steam and helps the puffs rise.
The step that matters
Let the mixture cool before adding the eggs. If the flour and butter mixture is still very hot, it can partly cook the eggs and cause lumps. Cooling it first lets the eggs blend smoothly into a uniform batter that rises evenly.
Swap the lemon
How well each one fits the dish's main ingredients (butter, milk, flour, egg, sugar):

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