Pastel de Choclo

Pastel de Choclo is a corn mash casserole. It uses cornmeal and pieces of corn mixed with onion and sometimes ground beef. There is always a little suprise baked into the middle...a whole olive, pit and all. You have to be careful you don´t bite into it without knowing. Also there is a sliced, hard-boiled egg too. I tried it at a restaurant but the texture doesn´t really float my boat.
