Ingredients
Directions
Prepare the starter
Pour your yeast into the flour and mix it to form a batter.
Lift out a heaped tablespoonful of this batter.
Put the batter into a bottle with 2 teaspoons of flour, 1 tablespoon of moist sugar, and ½ cup of lukewarm water.
Ferment
Cork the bottle and tie it down.
Let it sit for 48 hours.

What each ingredient does
- Batter
- Carries live yeast into the new mix to start fermentation.
- Flour
- Supplies starch that the yeast breaks down into food over time.
- Moist sugar
- Gives the yeast a quick food source, producing gas and flavour.
- Lukewarm water
- Hydrates the flour and sugar so the yeast can become active.
The step that matters
Use lukewarm water. Water that is too hot can kill yeast, while cold water slows fermentation. Lukewarm water keeps the yeast active so the starter develops properly.
