OK, I finally got around to documenting our results in the attempt to reproduce Calvin's Powder. Here is what we determined. We were just about out of our last bottle of Calvin's Powder, so we tried to come up with a reasonable replacement for it. We got the letter from Frank Hashek where Calvin lists the approximate list of peppers used in his powder. It is approximate since he states that "These pods and concentrations vary with availability.". So we set about collecting all the pepper types and doing taste tests of various combinations of peppers to try to find something similar to the Calvin's Powder that we had. Results: We think that we accomplished our goal and had many epiphanies along the way. I'll give the final recipe, but first a couple of the epiphanies. 1. Just about every combination we tried (about 10) was awesome! There is something about combining the powders that makes the result far superior to any of the peppers used. We dried and ground all the peppers in a coffee grinder (cleaned between each variety). Each powder was stored in a Freezer Zip Lock bag and they filled a 5 gallon can. The absolute best fragrance comes when you remove the lid from the can. The fragrance fills the room. 2. We smelled and tasted all 26 varieties of peppers that we used. The Wild Tepin had the best fragrance followed closely by Tabasco. The Bhut Jolokia and Naga Morich fragrances were vile. The Habaneros were all very distinctive and the only one that we could separately identify in the smell of the original Calvin's. All the rest were somewhat similar. 3. We did not like the taste of any individual pepper. Every blend was wonderful. We also made several blends adding combinations of garlic powder, onion powder, oregano and curry powder. These were also very tasty and we could visualize uses for each on vegetables, eggs, etc. 4. We finally concluded that we really liked nearly all of the blends. We feel that what Calvin discovered was that pepper blends are far superior to individual peppers. Why? We don't know. The recipe is not very important. Use 5-10 different varieties choosing heat levels that you like most and you will probably get something better than you can buy anywhere. Here is the blend that we feel hits the smell and taste of the original Calvin's Powder: 20% Rocoto/Manzano 10% Red Savina Habanero 10% Chinese 10% Tepin - wild 10% Aji Amarillo 10% Cayenne 10% New Mexican 10% Thai (Bird) 10% Tabasco All of these can be found on the internet except the Rocoto. This we had to search out at several Mexican markets as fresh peppers and dehydrate them ourselves. The Rocoto and Red Savina (or other habanero powder) are the only key ingredients. The others could be replaced. But even without the Rocoto, it would be a wonderful hot powder. BTW, the Wild Tepin are REALLY expensive. We have since planted a bunch of them and will do a lot more experimenting with them this fall. I have a LOT of pepper powders now, so if someone has an idea of a blend let me know. If it turns out good, I'll send you some. Tom Greaves
