Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. 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.
Make the dough
Pour hot milk over shortening, salt, and sugar.
Cool the mixture, then add the beaten egg, yeast cake, and flour.
Let the dough rise in a warm place until doubled in bulk, about 3½ hours.
Shape and bake
Roll out the dough gently on a floured surface and cut into oblong shapes.
Rub melted butter on half of each piece and fold over the other half.
Let the rolls rise again for about 2 hours.
Bake at 350°F (175°C) for 40 minutes.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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 gluten network that gives the dough its structure and chewy crumb.
- Yeast cake
- Produces carbon dioxide as it ferments, making the dough rise and become light.
- Egg
- Adds structure and richness to the dough and helps it bind.
- Milk
- Adds moisture and tenderness, and its proteins help the crumb brown in the oven.
- Shortening
- Adds fat that tenderizes the crumb and keeps the rolls soft.
- Sugar
- Feeds the yeast and adds sweetness and browning in the baked rolls.
The step that matters
Let the dough rise until doubled. Yeast needs enough time and warmth to produce gas and build structure. Under-proofed dough bakes dense, while over-proofed dough can collapse and lose its rise.
