I think you're missing the most important ingredient.. Tomatillos
You are mistaking what the OP is talking about. There are absolutely no tomatillos in it.
Here's my version OP,
I'll simmer jalapeos and Serranos with tops and stems removed (seeds are optional as well) along with a couple of garlic cloves in salted water until tender. You can simmer a little onion in there too, but, it's not necessary. Once cooking has finished, take that and put it in a blender or food processor and pulse a few times to desired consistency or pure it if that's what you prefer. Adjust salt as needed. It's literally that simple.
If you want to smooth it out a little, a drizzle of canola or grape seed oil can help, but, don't use a strong oil such as olive. You can throw in some avocado as well if you prefer, but, that will change it up quite a bit.
