Cut your 4 avocados in half lengthwise and remove the pit by striking it with your knife blade, then twisting gently. Scoop the flesh into a medium bowl using a spoon. Don't panic if a few brown spots appear—those are totally fine and won't affect your fresh guacamole summer.
Add the 2 tbsp fresh lime juice immediately to the avocados and gently fold it in using a fork. This prevents browning and adds that bright citrus flavor everyone loves. I don't mash it completely—I like little chunks throughout.
Fold in your finely diced red onion, seeded tomato, minced jalapeño, and minced garlic. Keep stirring gently until everything combines but still has texture. Mine always sticks a little to the fork and that's perfectly fine.
Add the 1/2 tsp ground cumin, 1/2 tsp salt, and 1/4 tsp freshly ground black pepper. Taste and adjust as you go—this is super important because everyone's salt preference differs.
Fold in your 2 tbsp chopped fresh cilantro and 2 tbsp olive oil until everything's incorporated. The oil helps keep it fresh and adds richness. Don't skip this step, I promise it makes a difference.
Transfer your fresh guacamole summer to a serving bowl and create a little indent in the center with the back of a spoon. This trick keeps it looking pretty at parties and prevents extra browning.
Serve immediately with tortilla chips, or cover with plastic wrap pressed directly onto the surface if you're making ahead. I've kept it fresh this way for up to 4 hours before guests arrive.
