Dry Yeast

Ingredients

Directions

Make the starter

  1. Tie hops in a cloth and place in a crock or bright stew pan.

  2. Pour boiling water over hops and steep for 15 minutes.

  3. Remove from heat and squeeze water from hops and set aside.

  4. Add flour, ginger, and sugar to the hot water.

  5. Ensure the mixture is hot enough to scald the flour.

  6. When cool, add dry yeast.

  7. Stir frequently.

Rise and thicken

  1. Each time it rises, stir it down again.

  2. Let it stand overnight.

  3. The next morning, stir as before until it forms a light foam.

  4. Thicken with cornmeal.

Shape and dry

  1. Shape into cakes.

  2. Dry in the shade.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ginger and sugar barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Hops
Provide bitterness and aroma that flavour the liquid before the yeast is added.
Flour
Supplies starch and body, thickening the mixture and giving the yeast food to work on.
Dry yeast
Ferments the sugars, producing gas that makes the mixture rise and foam.
Sugar
Feeds the yeast and adds sweetness, speeding fermentation.
Cornmeal
Thickens the mixture so it can be shaped into cakes.

The step that matters

Adding the yeast when cool. Yeast cells are killed by very hot liquid, so the mixture must cool enough before the yeast goes in, though it must still be hot enough to scald the flour.

Swap the ginger

How well each one fits the dish's main ingredients (hops, flour, sugar):

  1. Cinnamonfits better
  2. Jalapenofits better
  3. Gingerthe original
  4. Nutmegfits about as well

Fit is the average pairing score against hops, flour, sugar. Candidates are from the same food group and used in at least 100 recipes.
