Recipe ingredients
Ingredient notes
- Water: For best results, use water that is heated to 110 – 115 degrees Fahrenheit and use a thermometer. Any temperature between 75 degrees and 130 degrees should work, but yeast dies at 138 degrees. Some recipes use milk instead of water to activate yeast, so just follow your recipe.
- Sugar: Optional food for the yeast. Use the sugar from your recipe amount, not additional. If the recipe doesn’t call for sugar for blooming the yeast, you can still add it. Adding 1 teaspoon of sugar to a recipe that doesn’t call for it, for the purpose of feeding your yeast, won’t affect the overall taste of the bread. Honey or agave syrup work too.
- Yeast: Active dry yeast lies dormant and needs a warm liquid to become “activated.” Instant yeast, also known as quick-rise or rapid-rise yeast, does not need to be activated or “bloomed” before using. It’s ready to go as-is and simply gets incorporated right into your dry ingredients. Fresh yeast is not easily available, but if you happen to have the small cakes or bars of it, just crumble it into warm water like active dry yeast to activate.
Step-by-step instructions
- In a small saucepan, heat water to 110 degrees. Stir in sugar until dissolved and remove from heat. Add to a measuring cup and stir in yeast.
- Set aside to bloom until foamy, about 5 to 10 minutes.
Recipe tips and variations
- Yield: The measurements in this recipe are a guide to explain the process. Please follow the measurements in your particular recipe.
- Storage: Store open jars of yeast in the refrigerator for up to 4 months or in the freezer for up to 6 months. Use straight from the freezer (no need to thaw). Unopened packets of yeast can be stored in a cool, dry place.
- Expired: Your yeast should be bubbling and foamy within 5-10 minutes of activation. If it looks like nothing is happening, the yeast may be expired. Discard and try again with a fresh batch.
- Yeast freshness test: In a 1-cup liquid measuring cup, dissolve 1 teaspoon sugar in ½ cup warm water (between 110 and 115 degrees). Stir in 2 ¼ teaspoons (or 1 packet) yeast. After 10 minutes, the yeast should have risen to or above the 1-cup marker on the measuring cup.
