Choose and Prep Your Avocados: Cut the avocados in half and remove the pit. Scoop out the flesh into a medium-sized bowl.
Mash the Avocados: Using a fork or a potato masher, mash the avocados to your desired consistency.
Add Fresh Ingredients: Stir in the finely chopped red onion, tomatoes, jalapeños, and garlic. Sprinkle in fresh cilantro, and mix gently. Add sea salt and cumin, and stir again.
Add the Lime Juice: Squeeze the juice of two limes over the mixture and stir.
Adjust and Serve: Taste your guacamole and adjust the seasoning as needed. If you want it spicier, add more jalapeño. For extra richness, drizzle a bit of olive oil. Serve immediately or cover with plastic wrap pressed directly on the surface and refrigerate to prevent browning.
