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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and the whites, beaten separately and folded in, lighten its texture.
- Baking soda
- Reacts with the acidic sour cream to release gas, helping the waffles rise and turn tender.
- Sour cream
- Adds acidity and moisture, and activates the baking soda while giving a tender crumb.
- Flour
- Provides the structure that holds the waffle together once the batter sets in the iron.
The step that matters
Pour the batter onto the hot iron and turn it immediately. Batter poured onto a very hot iron starts setting at once, and turning it right away spreads it evenly before the surface firms. Waiting lets the batter cook unevenly and stick.
