c. 1900.  C. W. Greene, Lett. to Editor. When I was a youngster in Massachusetts, we called the gelatinous part of a baked maize pudding, the tom-alley. It somewhat resembles in appearance the tom-alley of the lobster; but in meaning it comes very near the Mexican, Cuban, and Southern U.S. use of tamauli or tamalli as the name of a kind of maize pudding.
