Why it works: Malt and potato work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 43 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
To Make Yeast Fob Ebbad
Ingredients
Directions
Make the yeast
Boil the hops in the water for 20 minutes.
Let it stand for about 5 minutes, then add to the bruised malt.
Cover and let the mixture cool to lukewarm.
Stir in not quite ½ pint of yeast and keep warm for 3 to 4 hours.
Bottle the yeast in small bottles, cork them well, and tie them down.
Make the dough
When ready to use, boil the potatoes without salt, mash them in the cooking water, and rub through a colander.
Stir in about 1 lb. of flour, then add the yeast, pouring it in the middle of the flour.
Let it stand warm overnight, and knead in the morning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Mashed potatoes supply starch and moisture, giving the dough a soft, moist crumb.
- Flour
- Flour forms the gluten network that gives the dough its structure.
- Yeast
- Yeast ferments the sugars in the dough, producing gas that makes it rise.
- Bruised malt
- Malt provides sugars that feed the yeast and add flavour and colour.
- Hops
- Hops add a bitter, aromatic flavour that balances the malt's sweetness.
The step that matters
Let it stand warm overnight, and knead in the morning.. The dough needs steady warmth so the yeast can ferment and build gas for rising. If it gets too cold, fermentation slows and the bread will be dense; kneading then redistributes the gas and develops gluten for an even crumb.
Swap the potato
How well each one fits the dish's main ingredients (hops, malt, flour):
- Mustardfits about as well
- Potatothe original
- Shallotfits about as well
- Lettucefits less well
Fit is the average pairing score against hops, malt, flour. Candidates are from the same food group and used in at least 100 recipes.
