Make your guacamole to your taste. Add as much or as little as you want of each of the ingredients.
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 tablespoon of the reserved lime juice. Let sit at room temperature for 1 hour and then serve.
