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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure so the waffles hold their shape when cooked.
- Sour milk
- Supplies moisture and acidity that reacts with the baking soda to help the waffles rise.
- Baking soda
- Reacts with the acid in the sour milk to release gas, lightening the batter.
- Melted butter
- Adds fat for richness, tenderness, and browning on the waffle iron.
The step that matters
Stir until thick like pancake batter. Stirring too much or too little changes the texture. Overmixing develops gluten and can make waffles tough, while a batter that is too thin will not hold its shape or crisp well on the iron.
