Ingredients
Directions
Make the batter
Sift the flour with the salt, baking soda, and cream of tartar.
Gradually add the sour milk, stirring until smooth.
If using, melt the butter and add it to the mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sour milk
- Its acidity reacts with the baking soda to produce gas, helping the pancakes rise.
- All-purpose flour
- Provides the starch and gluten structure that holds the pancakes together.
- Egg
- Adds structure and richness, helping bind the batter and set during cooking.
- Baking soda
- Reacts with the acidic sour milk to release carbon dioxide for lift and tenderness.
- Cream of tartar
- Adds acidity that supports the leavening reaction and helps keep the batter stable.
- Butter
- Adds fat for richness and a tender texture, and helps browning on the griddle.
The step that matters
Gradually add the sour milk, stirring until smooth.. Mixing too vigorously after the liquid goes in develops gluten and toughens the pancakes, while stirring just until smooth keeps them tender. Adding the milk gradually helps avoid lumps in the flour.
