Question: To prepare yeast for bread making.

  Options: 
 A. Heat up your water to 105 to 115 F. Then add in about 1 tsp. of sugar to the warm water. Next add in your yeast. You can agitate it a bit with a fork. Now let it sit for about 10 minutes until it gets nice and foamy/frothy. If after 10 minutes it isn't foamy, you need to start again. The yeast might be bad/old, or the water was too hot or too cold.
