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, and trap air from beating for lift.
- Sour milk
- Adds moisture and acidity that reacts with the baking soda.
- Baking soda
- Reacts with the acid in sour milk to release gas that makes the muffins rise.
- All-purpose flour
- Provides structure as its proteins and starches set during baking.
- Sugar
- Adds sweetness and helps the crumb brown lightly.
The step that matters
Gradually add the flour and mix until well combined. Mixing only until the flour is incorporated keeps gluten development limited, so the muffins stay tender rather than tough. Overmixing develops gluten and makes the crumb dense.
