Put a 6-8 quart stock pot on the stove at medium high and add about a tablespoon of olive oil. Put in the chopped onion and jalapeño and stir them together. While they are cooking finely chop 3-4 cloves of garlic and when the onion starts to get translucent add the garlic. Squeeze half of a lime onto the garlic. Mix it all together and add the salt, pepper, cumin and a pinch of cayenne pepper,, if you want. Yes, it adds a bit more heat to it but it also adds another flavor to the mix.
