We "discovered" Rao's nearly 20 years ago when it was not being sold outside of the northeast. It's been my go to jarred sauce ever since. Pricy, but does go on sale from time-to-time. I try to find the smaller jars as it will go bad after about a month in the fridge and we cannot always work through the large jars in that time.
Looks like I commented on this thread 12 years ago. Now that we live in Indiana, access to good Italian food is harder. My favorite pasta is ravioli from Durso's Pasta & Ravioli Company on Crocheron Avenue in Flushing, Queens.

My family has been hopping there since I was a little kid. I'd go with my grandmother who lived down the street. Whenever we drive back east (usually Christmas and Summer), I bring 3 empty coolers and stock up with their spinach, meat, and oso buco ravioli, along with their arancini, cauliflower fritters, roasted peppers, and semolina bread.
They were actually featured on Food Network's "Throwdown with Bobby Flay" for their ravioli several years ago. Bobby won. No justice.
