As I was saying, today on Facebook, one of my friends wrote about making the mistake of not washing her hands thoroughly after cutting up a hot pepper, and then touching her eye. A chorus of sympathy comments ensued, including comments that the burning sensation those peppers cause on one's skin is bad enough.
Of course, as some kind of domestic-doyenne-by-default, I had to put my quasi-expert advice in.
"Ow. I keep a box of medical gloves in my kitchen for stuff like that--also good for making burgers/meatloaf/meatballs
I also use the gloves when I am working with dough, and sometimes when I'm cutting up onions or handling raw fish, to avoid smelly hands.
Disclaimer: I've never actually cut hot peppers. I haven't made food involving them. Not that I'd rule out ever doing so, though I might used the canned chiles instead of fresh.
