To Make Yeast

Ingredients

Directions

Make the hop liquid

  1. Boil the hops in water until reduced to ½ quart.

  2. Strain the mixture through a sieve and add the salt.

  3. Return the hot water to the original vessel.

Make the starter

  1. Mix flour with cold water to achieve a thick molasses consistency.

  2. Boil the mixture for a few minutes, then remove from heat and let cool.

  3. When lukewarm, add yeast and let it rise.

  4. Transfer to a stone jar, leaving space at the top, and cover.

  5. The yeast will be ready for use the following day.

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

What each ingredient does

Hops
Add bitterness and aroma, and help preserve the liquid.
Flour
Forms a thick starter that gives the yeast food to grow on.
Yeast
Ferments the starter, producing gas that makes it rise and bubble.
Coarse sea salt
Seasons the liquid and slows unwanted microbial growth.

The step that matters

Let the mixture cool to lukewarm before adding yeast. Yeast is killed by high heat, so adding it while the mixture is still hot can stop fermentation. Lukewarm liquid stays warm enough for yeast to grow while remaining safe for the cells.
