"Traditional “Sunday gravy” is more than just meat sauce—it’s a labor of love, an all-day kitchen affair, involving several types of meat, a bunch of tomatoes, and at least one Italian grandmother. We wanted to honor this meaty extravaganza but shortcut the cooking so we could get this traditional dish on the table in a reasonable amount of time. When you’re using six or seven types of meat, the browning alone can take up to 40minutes. Our first step was to limit the dish to just one kind of sausage and one pork cut—plus meatballs. Hot Italian links gave the sauce a mild kick; baby back ribs were our favorite cut of pork because they weren’t too fatty and turned moist and tender in just a few hours. Meat loaf mix, a combination of ground beef, pork, and veal, produced juicy, tender meatballs, especially when mixed with a panade of bread and buttermilk. To further bump up flavor, we mixed in minced garlic, parsley, and red pepper flakes, plus an egg yolk for richness. To help the meatballs retain their shape we browned them first in a skillet before adding them to the sauce.?For the tomato sauce, canned crushed tomatoes were a winner, leading to a sauce with nice thickness and bright tomato flavor. Instead of merely browning the tomato paste for 30seconds, we cooked it until it nearly blackened, which concentrated its sweetness. The sauce was still lacking some beefy undercurrents; the best booster turned out to be the simple, straightforward addition of an ingredient rarely found in tomato sauce: beef broth...."
