Why it works: Buttermilk and flour 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 ↓
Waffles
Ingredients
Directions
Make the batter
The night before, stir the flour into the sour or buttermilk and let it sit overnight.
In the morning, beat the mixture for 10 minutes.
Add the molasses or brown sugar, melted shortening, and well-beaten eggs.
Dissolve the baking soda in a little warm water and add it to the mixture.
Cook and serve
Preheat the waffle iron and grease it thoroughly.
Pour a thin layer of batter into the hot waffle iron.
Cook until one side is browned, then flip the iron to brown the other side.
Serve hot with maple syrup.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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 batter that holds the waffle together once cooked.
- Eggs
- Add structure and richness, helping the waffles set and hold their shape.
- Sour or buttermilk
- Its acidity reacts with the baking soda to produce gas that lightens the batter.
- Baking soda
- Reacts with the acid in the sour milk or buttermilk to make the waffles rise and turn tender.
- Shortening
- Adds fat that gives tenderness and helps the waffles release and brown in the iron.
The step that matters
Dissolve the baking soda and add it to the batter. Baking soda must be fully dissolved so it reacts evenly with the acidic sour milk or buttermilk. Lumps leave pockets of unreacted soda and uneven rising and flavor.
“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.
