Been there done that and will never again peel in water. It washes off that roasted Chile flavor. Also last year we we drove to Mauro farms and bought Chile, I bought 4 sacks so I just had them roast it. Everything was fine and it was fun watching all those roasters in the back going like crazy. Then I saw how they finish the roast, they spray them down with high pressure water at the end, I though Noooo! But it was to late, my Chile was roasted and washed.
I’ll tell you, the Chile was fine for a couple months then started losing flavor noticeably. I chalk that up to the washing to peel. So much better flavor to peel by hand and don’t get to particular about all of those black specs. Flavor is way better and stays longer. That’s just my experience.
