There are plenty of ways to start this in advance. Four poblano chiles were roasted, skinned, seeded, and chopped, and those could be prepped and refrigerated until ready to make the sauce. I roasted them directly on top of a burner and turned them as they charred. The squash was cut into wedges and roasted in the oven with a coating of olive oil and sprinkling of salt and pepper. This could be done in advance, and the squash wedges can be reheated when you’re ready to serve. The next step in making the sauce was to broil a quartered white onion, 10 tomatillos with husks removed, a few unpeeled garlic cloves, and I added a couple of serrano chiles. Next, a cup of raw, hulled pumpkin seeds were toasted in a dry pan on top of the stove. Those toasted pepitas along with two cups of water were then pulsed in a blender. Next, the roasted onion, the peeled garlic, the chopped poblanos, my additional serranos, and some oregano, cilantro, epazote, parsley, and a pinch of anise seeds were to be added to the blender. This was way too much for my blender, and I pureed all of this in two batches. Salt was added to taste, and then the purred sauce was transferred to a large saucepan and simmered for about 15 minutes. The simmering really brought the flavors together. To serve, the roasted squash wedges were set in a pool of sauce and garnished with cilantro leaves and more toasted pepitas.
This recipe made a lot of sauce which is a good thing. I’m happy to have some stored in the freezer to use on enchiladas someday soon. And, it was delightfully tangy, spicy, and, herby with the squash. I’d never paired squash with these flavors before, and I’m so glad to have been introduced to the idea. There are several more ideas in the book I’ll be trying too.
