Why it works: Milk and butter 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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Mix the dry ingredients and sift twice.
Cut the butter into the flour.
Beat the egg.
Add the beaten egg to the milk.
Gradually mix the milk and egg into the flour with a knife to form a soft dough.
Toss the dough on a floured board, pat, and roll lightly to ½ inch thickness.
Shape and bake
Cut into oblong pieces.
Crease through the center of each roll lengthwise with a floured knife.
Brush the tops with egg white.
Sprinkle the tops with granulated sugar.
Bake at 400°F (200°C) for 12 to 13 minutes.

Flour and butter 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
- Flour
- Forms the structure of the dough once mixed with the liquids.
- Baking powder
- Releases gas during baking so the rolls rise and become light.
- Butter
- Cut into the flour to add fat, tenderness and flakiness to the dough.
- Egg
- Binds the dough and adds richness and structure to the rolls.
- Milk
- Adds moisture so the flour hydrates into a soft dough.
The step that matters
Gradually mixing the liquid into the flour. Mixing too vigorously or adding liquid all at once develops gluten, making the rolls tough. Stirring gently with a knife until just combined keeps the dough soft and tender.
