Yeast doughs that normally take an hour or more to rise at room temperature can be proofed in the microwave in about 15 minutes. Place the dough in a very large bowl and cover with plastic. Place an 8-ounce cup of water in the back of the microwave with the bowl of dough in the center, and set the power as low as possible (10 percent power). Heat for 3 minutes, then let the dough rest in the microwave for 3 minutes. Heat for 3 minutes longer, then let rest for 6 minutes. The dough will double in bulk.
