Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat for richness and a tender crumb.
- Soda
- Reacts with the acidity of sour milk to produce gas that helps the cake rise.
- Raisins
- Add chewy texture and concentrated sweetness.
- Eggs
- Add structure and help bind the batter.
The step that matters
Combining the soda with the sour milk. Soda needs an acid to react and release carbon dioxide. The sour milk supplies that acid, so the soda must be fully mixed in to lift the batter evenly. Too much soda leaves a bitter, soapy taste and can make the crumb coarse.
Swap the raisin
How well each one fits the dish's main ingredients (butter, egg):
- Lemonfits better
- Vanillafits better
- Coconutfits better
- Raisinthe original
Fit is the average pairing score against butter, egg. Candidates are from the same food group and used in at least 100 recipes.
