Dissolve 2 ¼ tsp (1 pkg) active yeast in warmed ¼ cup filtered water in a measuring cup, cover, and let rest for 10 minutes. The yeast should froth and grow at the top.
While waiting for the yeast to grow, stir together one cup of the 3 cups all purpose flour, one cup of the 3 cups white granulated sugar, one cup of the 3 cups milk in a large bowl or half-gallon mason jar until all clumps are broken up. Make sure your jar is large enough to grow through the ten days.
