here is a more extensive explanation of Desflemar. hope this helps
Desflemar: To Neutralize by Soaking This refers to taking the "bite" out of a hot fresh chile, or even a strong onion, by soaking in a solution of water with either vinegar or salt, both of which draw out the heat. If handling a fresh chile causes either coughing or watery eyes, this is a good indication that the chile will be quite hot, and soaking for one-half to one hour will help to neutralize it. Fresh jalapeņos being prepared for stuffing may be soaked overnight in milk after being seeded. that is according to mexconnect.com
Thanks. I have heard of the technique, but never knew the name for it.
