Name: Excellent Dairy-bread, Made Without Yeast
Ingredients: 1 teaspoon pounded sugar; 50 grains pure carbonate of soda (about 1 teaspoon); ¼ teaspoon coarse sea salt; 1 pound flour; sour buttermilk (enough to make a firm dough)

Why it works: Flour and buttermilk are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 3,721 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Excellent Dairy-bread, Made Without Yeast

Oven, in the book's wordsA fierce oven

Ingredients

1 teaspoon pounded sugar
50 grains pure carbonate of soda (about 1 teaspoon)
¼ teaspoon coarse sea salt
1 pound flour
sour buttermilk (enough to make a firm dough)

Directions

The book says “a fierce oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the dry mix

Blend the sugar and carbonate of soda together.
Mix the salt with the flour in a bowl.
Sift the soda and sugar mixture into the flour.

Make and bake the loaf

Stir well and quickly form a firm dough with the sour buttermilk.
Bake the loaf in a preheated oven at 400°F (200°C) for about 50 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour: Forms the main structure of the loaf once mixed with liquid.
Carbonate of soda: Reacts with the acid in sour buttermilk to produce gas that lifts the loaf.
Sour buttermilk: Provides the acid that activates the soda and moisture to bind the dough.
Pounded sugar: Adds sweetness and helps the crust brown in the oven.

The step that matters

Stir well and quickly form the dough. Carbonate of soda starts reacting as soon as it meets the acidic buttermilk, so the dough should be mixed briefly and put into the oven promptly to keep the gas that lifts the loaf.
