Big-Batch, All-Day Pasta Bolognese
*What's an umami bomb?
Chef Howard Hannah explains: “A Parmesan rind, a chunk of salami, a handful of dried porcini mushrooms or a few anchovies. What all of these have in common is a deep, full savoriness that’s more of a feeling than a flavor. Throw in whatever you have on hand. If you see them later, fish them out. But if they melt away and break down into the sauce, just leave them in.”
