Proofing the yeast means we'll be adding it to the water and making sure it's alive and healthy. Yeast
is a living organism that eats sugars in your dough and turns it into carbon dioxide. This causes your dough to rise as the carbon dioxide creates bubbles in your dough.
You'll need to heat your water to 110° F (45° C) to create a nice warm, but not too hot environment for your yeast to grow. Pour the water into your mixing bowl and sprinkle the yeast over the water. By sprinkling it we're allowing more of the yeast to come in contact with the water.
Let the yeast set for 10 minutes until it's nice and bubbly. If your yeast didn't get frothy, you may have a bad batch of yeast. If this happens, you should try again with a different pack of yeast, so you don't ruin your bread.
