Jalapeno's aren't that hot. The heat rating on habanero's is about 10 times more than a jalapeño. I grow my own and the stuff I grow would be 10 to 20 times the heat of a jalapeño. When you clean and cook really hot peppers you wear gloves and you still don't touch your face because the capsicum will soak through the gloves after a few minutes. It's wonderful.
When you eat jalapeno it's not that hot. When you rub it in your eye it is plenty hot.. I love hot peppers and cook with jalapeno, habanero, scotch bonnet, even bhut jolokia. Try not to disrespect them, or it bites you back
Last night my younger brother was visiting and decided to make a snack. He selected some macaroni and cheese, and used some of my hot sauces out of the fridge without asking. With a light splash of Death By Johnny and a few drops of Ghost Pepper sauce, he completely ruined 2 boxes of mac and cheese. It was rendered inedible, so incredibly hot that 1 bite gave me indigestion and had me sweating. Rookie mistake!!
