Great stuff! Grew up in a heavily Italian neighborhood in SNJ about 10 miles SSE of South Philly, where a ton of South Philly Italians moved to in the 50s and 60s, so a couple of my best friends growing up had moms who made the best freakin' food. I'll never forget going to some of their 7-course holiday meals. So good. Our neighborhood also used to do block parties with about 15-20 families every 4th of July and Labor Day and there was some incredible Italian food and always a ton of fresh seafood, plus there would always be bocce ball games going on. I recall eating dozens of steamers and raw clams and a ton of fried calamari every year (hey it was free, lol).
Also, had a coworker for years whose parents were from Italy and he used to describe how they'd all get together (him and his 3 siblings with the parents and grandkids) and spend a whole weekend doing exactly what your video showed, making a few hundred jars of sauce. I got one once and it was amazing. Love Italian food - also a big fan of Lidia Bastianich's show on PBS (and her restaurant, Becco, in NYC).
