You can wear disposable surgical gloves. Or just put the whole habaneros on a hot comal and char them and then just pull off the stem before putting everything in the blender.

I grew them in my garden several years back and was thrilled to see several beautiful ripe ones while weeding the garden . i picked them, slipped them in my pockets then kept on working and sweating and working and sweating.....i thought it was fire ants at first and that they had somehow crawled up my legs to my crotch without my noticing. The skin comes off like a bad sun burn on the second day.

A sure fire way of getting rid of the cootys
