And a Note on Tall Steamers

If you are cooking for a mob and have cause to stack a pile of steamers on the order of the great Dr. Seuss cat who walks about under a mountain of hats, then you may question how the bottom layer will steam relative to the top. If the heat source is strong enough to generate a healthy steam clear to the top, then the top story and the bottom story will steam to doneness in the same time, and there will be no need to rotate them. If the heat source is weaker, then stack up the steamers only so far as the gush of steam permits. There is nothing worse than food that is left to sweat slowly away in a weak puff-puff of steam. If the heat source on which the process depends only generates enough steam for two layers, then stack them no higher!
