Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw potatoes
- Supply starch and moisture that form the bulk of the batter.
- Flour
- Adds body and structure to the mixture as it thickens.
- Sugar
- Feeds the yeast and adds sweetness to the bread.
- Yeast
- Produces gas as it ferments, making the mixture rise.
The step that matters
Add the yeast when the mixture is warm. Yeast works best at moderate warmth. If the mixture is too hot it can kill the yeast, and if it is too cold fermentation slows and the dough may not rise.
Swap the potato
How well each one fits the dish's main ingredients (flour, sugar, hops):
- Mustardfits better
- Arrowrootfits better
- Parsnipfits better
- Potatothe original
Fit is the average pairing score against flour, sugar, hops. Candidates are from the same food group and used in at least 100 recipes.
