John, Glad that site helped you in your quest. I find reading all the posts about the scientific stuff that relates to chiles/capsicum interesting, just not my cup of tea. I trade/start/grow/harvest/preserve/cook/eat El Grande & that's enough knowledge for me. Would assume your thought that (snip) "This explains why roasting peppers in a direct flame or very hot grill lessens the *heat* of the peppers." is correct. I've noted that Habs loose heat if I simmer them in vinegar/salt before preserving as compared to putting a couple of slices in pepper, stuffing in jar & filling jar with mixture. I used Risa's Tabasco recipe* on a number of different pepper types this season & feel the double cooking made a BIG difference in the heat of the finished product. Of course this is a very "unscientific" observation that will probably (hopefully) kick off another one of those "scientific" discussions of molecules & other "stuff" that I like to read about. Hotty Holidays, Paul (The NorthEast ChileMan) * Snipped portion of Risa's Tobasco Recipe: In a small nonreactive saucepan (I used Visions by Corningware), boil the chiles and garlic in the vinegar until tender. Place in a blender with the salt and sugar and puree. Run through a metal sieve if necessary. Dilute this paste with more vinegar until it is the consistency of rich cream. Pour into a nonreactive saucepan, bring to a boil, ----- Original Message ----- From: "Love2Troll" <Love2Troll@kc.rr.com> > Snipped >> Pure capsaicin melts at 65°C (149°F) and boils at 210-220°C (410-428°F).<< > > Thank you Paul for your very informative post. > > I've been trying to find the vaporization point of capsaicin for some time. This explains why roasting peppers in a direct flame or very hot grill lessens the *heat* of the peppers. At least I think that it does. I had thought that the boiling point was aprox 50-60°C less than stated. > > JohnT
