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 ↓

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
- Eggs
- Add structure and richness, helping the batter bind and set as the waffles cook.
- Baking powder
- Releases gas when heated, lifting the batter so the waffles rise and stay light.
- Flour
- Provides the starch and protein that form the waffle's structure once cooked.
- Milk
- Supplies moisture that hydrates the flour and keeps the batter pourable.
- Butter
- Adds fat for tenderness and flavor, and helps the waffles brown in the iron.
The step that matters
Gradually add flour until the batter is rather thick. Adding flour in stages lets you judge the consistency. Too much flour at once makes the batter dense and tough, while too little makes waffles thin and limp.
