There's a Day for everything and March 20th is for celebrating ravioli and in St. Louis that automatically means the toasted kind. I mean seriously, if you live in the STL metro area toasted ravioli is an invited guest at almost every function, wedding, buffet and menu.
It's not entirely clear how toasted ravioli originally came about, at least 2 St Louis restaurants have the best claim-Charlie Gitto's on The Hill and Mama Campisi's on The Hill. In any event the tasty toasties are here to stay and it's too bad the rest of the country can't enjoy them.
You can buy frozen toasted raviolis in any local grocery store but if you're looking for authentic, try stopping by Mama Toscano's on The Hill some day. They are a ravioli factory, making thousands each day of every variety, not just toasted. They sell to many restaurants, but love selling walk ins a pound or two. They are fresh and soft, dusted with flour and take about 30 seconds to heat in hot water. The toasted are pillowy squares and so good. If you go out to eat a lot and order the toasted ravs you'll soon be able to distinguish the Toscano varieties because they're smaller, shaped a bit narrower and are puffed and soft.
So celebrate the ravioli St. Louis.
