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 ↓
French Rolls
Ingredients
Directions
Sift the flour into a bowl and make a hollow in the center.
Mix the yeast and warm milk or water, then pour into the hollow.
Add sugar, salt, egg yolk, and melted butter; stir until half the flour is incorporated.
Beat the batter thoroughly, then gradually mix in the remaining flour while beating.
Knead the dough on a floured surface until smooth.
Brush a pan with a small amount of melted lard and place the dough inside, brushing the top as well.
Cover with a cloth and let rise in a warm place until doubled in size.
