I use this sauce in lots of different things I cook
Unlike a quick Neapolitan coulis made with raw tomatoes and a fleeting fifteen-minute simmer, Sicilian red sauces frequently lean into heavy aromatic foundations and extended reduction times. Historical records from the Mediterranean trace this technique to preservation methods used before refrigeration, where long cooking drove off excess moisture and concentrated natural sugars. Olive oil and butter combine here to bridge two culinary traditions: the southern coastal preference for plant fats and the northern inclusion of dairy. Simmering this mixture for four hours transforms the chopped and crushed tomatoes into a cohesive, velvety base.
Water content dictates sauce consistency, making evaporation critical during the extended simmer in a stockpot. Crushed tomatoes release massive amounts of liquid, which must reduce gradually over low heat to prevent scorching at the bottom of the vessel. Fat distribution relies on temperature control; adding butter at the very end rather than the beginning stops the milk solids from separating and browning too heavily. Chop onions uniformly to 1/4-inch pieces so they soften evenly alongside minced garlic without burning during the initial sauté phase.
