All you do is measure out the yeast and mix it with the water called for in the recipe. Yeast is happiest at about 75Â°-80Â°, so the water should feel barely warm or lukewarm to the touch. Add just a pinch of sugar to give the yeast something to munch on. Let the yeast and water sit for a few minutes. First, the water will dissolve the dry coating around the granules of yeast, releasing the active yeast inside.
