Why it works: Potato and sugar are a kitchen classic. They rank in the top 30% of all ingredient pairs, and cooks put them together in 3,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Bread and Breakfast Cakes. Yeast.
Ingredients
Directions
Make the starter
Boil 2 quarts of water with 2 tablespoons of hops.
Strain the boiling water over the grated potatoes and stir well.
Boil the mixture once more.
Add ½ cup of sugar and ¼ cup of coarse sea salt.
Let the mixture cool to blood-warm, then add 1 cup of yeast.
Rise and store
Allow it to rise in a warm place for 5 to 6 hours.
Once well-risen, transfer to a stone jug.
Cork the jug tightly and store it in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Supply starch and moisture that feed the yeast and give the mixture body.
- Yeast
- Ferments the sugars and produces gas, making the mixture rise.
- Sugar
- Provides food for the yeast, speeding fermentation and adding mild sweetness.
- Hops
- Adds bitterness and aroma and helps preserve the liquid.
The step that matters
Cool to blood-warm before adding the yeast. Yeast is killed by very hot liquid, so the mixture must cool to about body temperature before the yeast goes in. Too hot and it will not rise; the warm rise that follows then depends on live yeast working in gentle heat.
Swap the potato
How well each one fits the dish's main ingredients (hops, sugar):
- Mustardfits better
- Cucumberfits about as well
- Capsicumfits about as well
- Potatothe original
Fit is the average pairing score against hops, sugar. Candidates are from the same food group and used in at least 100 recipes.
