The secret is the lime juice!

4 ripe avocados
1 lime, juiced
½ medium onion, finely chopped
1 clove garlic, minced
1 vine-ripe tomato, diced
¼ teaspoon ground cumin
¼ teaspoon chili powder
Kosher salt and freshly ground pepper

Halve and pit the avocados then mash them with a fork, leaving them a bit chunky. Add the remaining ingredients and gently fold everything together.

Lay a piece of plastic wrap on the surface of the guacamole so it doesn't brown and refrigerate for at least one hour before serving.
