Why it works: Flour and ginger are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 8,564 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Yeast That Won't Sour

three quarts

Ingredients

Directions

Make the hop mixture

  1. For three quarts, take two handfuls (as much as you can hold) of hops, one teacup of flour, half a teacup of salt, half a teacup of white sugar, and two large tablespoonfuls of ginger.

  2. While the hops are boiling, mix the above with a little cold water, strain the hop water, wash out the kettle, pour all in the kettle again, stirring all the time to keep from burning; it will be thick and smooth.

  3. Boil thoroughly.

Add the yeast

  1. Have the yeast jar perfectly clean.

  2. Pour in the cooked batter and set away to cool.

  3. When cool enough not to scald the yeast, put in a tea‑cupful of yeast.

  4. When light, tie up tightly and set on the cellar floor.

What each ingredient does

Flour
Thickens the batter so it becomes thick and smooth as it cooks.
White sugar (in the method)
Provides sweetness and food for the yeast to feed on.
Yeast (in the method)
Ferments the batter so it rises and becomes light.

The step that matters

When cool enough not to scald the yeast, put in a tea‑cupful of yeast.. Yeast is killed by high heat, so the batter must cool to lukewarm before adding it. Adding yeast to hot liquid can destroy its ability to ferment and leaven the batter.
