I like Alton Brown's guacamole recipe:
3 Haas avocados, halved, seeded and peeled
1 lime, juiced
1/2 teaspoon kosher salt
1/2 teaspoon ground cumin
1/2 teaspoon cayenne
1/2 medium onion, diced
2 Roma tomatoes, seeded and diced
1 tablespoon 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 tablespoon of the reserved lime juice. Let sit at room temperature for 1 hour and then serve.
I also really like the vacuum-packed guac they carry at Costco (you can also find it in the produce section of your local grocery store, usually). Very tasty, and you can freeze the packages until you need to use them.
Another interesting way to eat your avocados, courtesy of Alton Brown (again):
Avocado Compound Butter:
6 ounces ripe avocado meat, approximately 2 small avocados
1 tablespoon freshly squeezed lemon juice
2 ounces unsalted butter, softened
1 garlic clove, minced
1 tablespoon freshly chopped cilantro leaves
2 teaspoons ground cumin
Kosher salt and freshly ground black pepper
Peel and pit the avocados. Place all ingredients into the bowl of a food processor and process until well combined. Place mixture onto a sheet of parchment paper and shape into a log. Place in the refrigerator for 3 to 4 hours. Slice and serve with grilled fish or chicken.
