Shanna's How To Steam Tamales
TO STEAM THE TAMALES: Set steamer over high heat. When steam puffs out,
reduce the heat to medium. Steam 1 hour 15 minutes, adding more water when
necessary. To check for doneness, unwrap a tamale: If ready, dough will come
free from wrapper and feel soft. If dough sticks to wrapper, rewrap, and steam
15 to 20 more minutes. Remove from heat; let stand 15 minutes for batter to firm
up. They will remain warm for about 1 hour.
