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 ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Scald the milk and add the butter.
Cool the mixture.
Stir in the sugar, salt, and yeast.
Mix in enough rye flour to form a stiff dough.
Cover and let the dough rise overnight.
Shape and bake
In the morning, shape the dough into small loaves and let them rise again.
Bake in a slow oven at 300°F (150°C) for 45 minutes.

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
- Rye flour
- Forms the stiff dough structure that holds the loaves' shape.
- Yeast
- Produces gas during the long rise, leavening the dough.
- Milk
- Adds moisture and softness to the dough.
- Butter
- Adds fat, contributing tenderness and richness to the crumb.
- Sugar
- Feeds the yeast and adds a little sweetness and browning.
The step that matters
Overnight rise. The dough must rise slowly and fully before shaping; rye flour has little gluten, so it relies on yeast gas and a stiff consistency to hold its structure. Underproofing or a dough that is too wet will give dense loaves.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
