If you go to the Fair...pick up one of these....
Amazon.com: Progressive International Manual Food Chopper and Salsa Maker: Kitchen & Dining or something like it. They make things really easy and fast.
I go with, white or yellow onions, spring onions or chives, you got the tom's, garlic, cilantro, whatever type/amount of peppers you want for heat and flavor, fresh lime juice, a little salt and believe it or not, a little sugar.
I usually make 3 heat levels at a time---0----50 and where did your eyebrows go?
