Potato Yeast

Ingredients

Directions

Prepare the potato mixture

  1. Boil the potatoes until tender, then peel and weigh them.

  2. While hot, finely bruise the potatoes and mix with boiling water, using 1 quart of water for each pound of potatoes.

  3. Rub the mixture through a fine sieve.

  4. Add honey or brown sugar, using 1 ounce for each quart of water, and boil until it reaches a batter‑like consistency.

Add yeast and rise

  1. Allow the mixture to cool slightly, then add 2 tablespoons of yeast for every quart of water.

  2. Cover with a cloth and let it rise overnight.

Store

  1. Store in a bottle for future use, pouring off any thin liquid on top.

  2. Make fresh yeast every 2‑3 months.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mealy potatoes
Provide starch and body that the yeast feeds on to build the starter.
Honey or brown sugar
Feeds the yeast with sugar, encouraging fermentation and rising.
Yeast
Ferments the starch and sugar, producing gas that makes the starter rise.

The step that matters

Cooling before adding the yeast. If the mixture is still very hot, it can kill the yeast. Letting it cool slightly before adding the yeast keeps the cells alive so they can ferment properly.
