The Best Guacamole Recipe in the World.

I originally found this via Alton Brown at the Food Network, but that website doesn't keep all recipes online for some reason. Thankfully, some people are awesomer than I and didn't lose their hard copy version of the recipe. I've now used this recipe at my second social gathering (New Year's Eve), and it received a response as enthusiastic as its debut (Super Bowl Sunday). If the Food Network won't do it, then I will:

3 Haas avocados, halved, seeded and peeled
1 lime, juiced
1/2 teaspoon kosher salt
1/2 teaspoon ground cumin [<---- THIS IS THE MONEYMAKER.]
1/2 teaspoon cayenne
1/2 medium onion, diced
2 roma tomatoes, seeded and diced
1 tbsp chopped cilantro
1 clove garlic, minced

In a large bowl place the scooped avocado pulp and lime juice, toss to coat. Drain, and reserve the lime juice, after all of the avocados have been coated. Using a potato masher add the salt, cumin, and cayenne and mash. Then, fold in the onions, tomatoes, cilantro and garlic. Add 1 tbsp of the reserved lime juice. Let sit at room temperature for one hour and then serve.

EDIT: Holy carp! I put the moneymaker tag on the wrong ingredient. It is now correct.
