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 ↓
Egg Rolls
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Rub the butter into the flour.
Add baking powder and salt.
Beat the egg until light, then mix in the milk.
Combine the egg mixture with the flour mixture and mix lightly.
Shape and bake
Roll out the dough on a floured surface and cut into oblong pieces.
Make a deep crease through the center of each roll with a floured knife.
Brush the tops with egg white and sprinkle with granulated sugar.
Bake for 16 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Coats flour particles and adds richness and tenderness to the dough.
- Flour
- Forms the structure of the dough once mixed with liquid.
- Baking powder
- Releases gas in the oven so the rolls rise and become light.
- Egg
- Adds structure and richness, and the white gives the tops a glossy finish.
- Milk
- Hydrates the flour and adds moisture and softness to the dough.
- Granulated sugar
- Adds sweetness and helps the tops brown slightly in the oven.
The step that matters
Mixing the egg and milk into the flour. Mixing lightly keeps gluten development limited, so the rolls stay tender instead of tough. Overworking the dough makes the baked rolls dense.
