This Bolognese uses the fat of the pork to balance the leanness of the lamb while keeping the lamb’s distinct flavor. I love the sound of this sauce cooking: the light pop a single bubble of steam makes as it escapes every 15 seconds or so. It’s the sound of a low simmer; the sound of an incredibly delicious slow-cooked sauce sitting on the stove. Be sure to use a large pot, as this recipe makes more than you’ll likely need, but it freezes exceptionally well stored in an airtight container for up to 1 month.
