Dissolve Yeast

All about yeast

Bread Baking 101

For Active Dry & Optionally, Fresh Yeast: Yeast is dissolved in warm water to revive the yeast cells prior to its use in a recipe. Milk or liquid sweeteners do not work well. If you do not like the process, use Instant Active Dry Yeast, which is added to the dry ingredients.

Activate the Yeast for Use in the Recipe: 

Note: If you have previously proofed part of the yeast, combine it with the remainder of the dissolved yeast and water

Do not add salt directly to the dissolved yeast as salt will kill it. Instead dry-blend it in with the second cup of flour and then add both to the recipe. 

1. Sprinkle the yeast granules, instant or active dry or crumble cake yeast over the surface of 110 - 115 degrees F liquid, preferably water; no more and no less. (Don't dissolve yeast in milk because it lumps easily. For tips). Instant Active Dry Yeast is added with the dry ingredients to the recipe.

Measure the water's temperature with an Instant Read Thermometer right before you add the yeast. (Some yeast packages recommend different temperatures; always follow the instructions on the packet or box.)

If the water temperature is too low, or below 110 degrees F, the yeast will be inhibited. If too high, starting at a minimum of 120 degrees F, it starts killing the yeast. At 140 degrees F, when the yeast is fully done in, the water feels really hot.

My mother did not have a thermometer to test the water temperature for dissolving yeast in; she just dropped water on inside of her wrist to test. When it felt warm but not hot -- like a warmed milk from a baby bottle -- she used it. My grandmother tested the water's temperature by taking a teaspoon full of warm water and putting it up to her chin. She taught me that if it felt slightly warm, it's perfect for dissolving yeast in. I like to use an Instant Read Thermometer which I find to be perfect for me -- so each to their own!!

Active dry yeast contains the greatest number of inactive cells. They tend to clump around the activated ones and take the longest to dissolve.

I like to stir the mixture with a chopstick, a skewer or the handle of a table spoon or fork; yeast sticks easily to any surface dipped into the mixture and you want to minimum the surface area. If the yeast clumps, let it sit a few seconds to dissolve some more and try stirring again.  

DO NOT add in the salt here, or it will kill the yeast. 2. Let the yeast sit in the water for a few moments to absorb the water, and then stir until dissolved. This takes 1 - 2 minutes or less. If the yeast clumps, let it sit a few seconds and try stirring again.

3. After another 2 or 3 minutes, the yeast will have absorbed enough liquid to become active and bubble. Cake yeast will start to soften. Use in the recipe right away. Adjust the recipe for the water and yeast used.

4. If adding in milk, eggs, melted butter, etc, directly to the yeast, make sure ingredients are at room temperature, not cold or hot. Cold or hot can shock and inhibit the yeast.

Q: My yeast doesn't bubble or foam ? A: If the yeast doesn't foam after 5 to 6 minutes, throw it out. Your yeast has probably expired, or the water temperature was too cold or too hot. Throw it out and start again.

Always pay close attention to yeast's expiration date printed on the package and test it before using.  

An instant read thermometer or candy thermometer is essential in determining the water's temperature. It is available from grocery or cookware stores. Or, the water or liquid temperature should be comfortable when placing a few drops on your wrist. 

A quick way to get my water to the right temperature (110 - 115 degrees F) is to measure it under a running faucet. I simply turn it on and place the end of an instant read thermometer in the water stream. When the thermometer measures the correct temperature, the water can be used. When you fill the measuring cup, measure the temperature again right before using; a cold room or measuring cup can lower it a few degrees.
How to add scalded milk to the dissolved yeast: Yeast really clumps up when added to milk. To solve this, first dissolve the yeast in 1/4 cup of 110 - 115 degree F water and let it sit until it bubbles. If you have instant nonfat dry milk powder, add in enough needed to make 1/4-cup liquid; do not add water. Bend it in with the flour. Then add in the scalded milk, less 1/4-cup, warmed to the same temperature.
SUGAR: Some recipes call for adding the sugar to the yeast and liquid mixture, or others call for adding the sugar in with the dry ingredients.  Either method is fine. There will be a vigorous foam if sugar is added to the yeast/liquid mixture, but be careful because a high concentration of sugar will kill it.
