Why it works: Molasses and flour are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 10,429 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
Make the hop water
Tie the hops in a thin bag and boil them in water.
Add the coarse sea salt and molasses.
Thicken and cool
Make a thin paste with flour and cold water.
Remove the hops and gradually pour the paste into the hop-water.
Place it over the fire and let it boil for a few minutes.
Let it stand until lukewarm, then add some old yeast.
Store
Once it is light, store it in a cool place.

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, and help preserve the starter.
- Flour
- Forms a thin paste that thickens the liquid and gives the starter body for the yeast to work in.
- Old yeast
- Supplies live microorganisms that ferment the liquid and make it light.
- Molasses
- Adds sugar that feeds the yeast and contributes flavour and colour.
The step that matters
Let it stand until lukewarm before adding the yeast. Yeast is killed by high heat. Adding it while the liquid is still hot can destroy the cells, so the starter fails to rise. Cooling to lukewarm keeps the yeast alive and active.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
