Look what I found at the market today! The owner says they bring hatch chiles in every year. They also had green and red hatch powders and Ristras that are still drying. Right on time for Posole season.
To answer your question, no I don’t think anyone would go through the trouble of removing seeds and adding them back. I’m willing to bet they’re using a meat grinder or something similar. The previous photo is of flakes I bought from the store so it’s not just a pretty photo it’s how it comes.
They sell a grinder attachment that fits on their bottles to address this issue. I haven’t tried any of their products but I like what they’re doing with the blends.
