Why it works: Sugar and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
To Pcrify Yeast for Bread or Cakes
Ingredients
Directions
Wash the yeast
Mix the yeast with a large quantity of cold water.
Let it sit in a cool place overnight.
Drain off the water and stir the yeast with more fresh water.
Let it stand for several hours until the water is clear.
Change the water daily in winter and twice daily in hot weather.
Revive weak yeast
If the yeast ferments less, stir in a small portion of brown sugar and warm milk 15-20 minutes before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Provides the living cells that ferment and make the dough rise.
- Cold water
- Rinses the yeast so residue and impurities wash away from the cells.
- Brown sugar
- Gives the yeast a ready food source to restart fermentation.
- Warm milk or other liquid
- Adds warmth and moisture to help the yeast become active again.
The step that matters
Changing the water on schedule. Spent liquid and waste products build up around the yeast and slow it down. Replacing the water with fresh liquid at the stated intervals keeps the yeast clean and active.
