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 ↓
To Make Dky Yeast for the Summer
Ingredients
Directions
Make the starter
Boil the bag of hops with the sliced potatoes in 1 gallon of water for 1 hour.
Allow the mixture to cool, then add 1 cup of sugar, ¾ cup of salt, and ½ cup of baker's yeast.
Shape and dry
Mix in enough Indian meal to form a stiff dough.
Shape the dough into rolls and cut into ½ inch thick cakes.
Dry the cakes in moderately cool air on a frame covered with mosquito netting.
Cover the cakes with netting while drying to keep flies away.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Starch and moisture that feed the yeast and help bind the mixture.
- Hops
- Add bitterness and aroma, and slow spoilage in the liquid.
- Baker's yeast
- Ferments sugars to produce gas that lightens the dough.
- Sugar
- Feeds the yeast so it becomes active and adds sweetness.
- Indian meal
- Absorbs liquid and forms the stiff dough that holds its shape.
The step that matters
Cool the mixture before adding the yeast. Yeast is killed by high heat, so the boiled liquid must cool enough before the yeast goes in to stay alive and work.
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.
