I mainly use romas but prefer the San Marzanos as they're larger. Funny thing is no one around here had San Marzanos for sale. Had to order them online so got 6 plus a pack of seeds to start mine own next year. If I have some grape tomatoes laying around as well as the regular kind I'll throw them in too just to use them up. I don't make tomato sauce but salsa and spaghetti sauce. I have a machine that separates the skins and seeds from the pulp so makes life easy when it comes time to canning for me.
