Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Yolk enriches the batter and the whipped white lightens it for a tender crumb.
- Sour milk
- Its acidity reacts with the bicarbonate of soda to produce gas for rising.
- Bicarbonate of soda
- Reacts with the acid in the sour milk, releasing carbon dioxide that lifts the muffins.
- Flour
- Provides the structure that sets as the muffins cook.
- Melted butter
- Adds fat for richness and a tender texture.
The step that matters
Gently fold in the beaten egg white and cook immediately. Folding keeps the air in the whipped egg white, and the soda and acid gas starts as soon as they mix, so delaying the bake lets much of the lift escape.
