Okay, I could not have been more wrong about my Cajamarca chiles. I just picked the pod you see here, a dark orange one from near the top of the bush, so I know it's one of the newer ones. As you can see from the color of the placenta, there is plenty of capsaicin in this pod. The taste test bears that out—Heat level is as strong as any Orange Habanero I've ever tasted, and the taste and aroma have a good punch—as you said, Greg, kind of hab-ish, but with another type of spice flavor I can't identify. So why did the earlier chiles taste much milder? Don't know. Why do the darker red, riper pods seem to have less flavor? Don't know that one either, but it seems that most all the chiles in the garden taste better, and are larger and hotter, since the weather cooled off.
Yea, its always pretty bizarre towards the end of the season, different sizes, shapes and heat levels....
Here's a different comparison, (non chilli) my Roma Tomatoes were averaging 2/3" all season but these were picked 2 weeks ago from the same plants......go figure
