Guacamole with mango and pomegranate

Yeti made this last week for Wednesday dinner, and it was awesome. I'm glad I hadn't read the recipe before I ate some, because I probably would have been scared away by the raw onion. But I don't even remember tasting it. Good stuff!

4 ripe avocados (about 2 lbs.)
1 cup finely chopped white onion
2 fresh serrano chiles, finely chopped (2 tablespoons), including seeds
1/4 cup fresh lime juice, or to taste
1 1/4 teaspoons salt
3/4 cup pomegranate seeds (from 1 pomegranate)
3/4 cup diced peeled mango
1/2 cup chopped cilantro
Lime wedges to garnish

Halve, pit, and peel avocados. Coarsely mash in a bowl. Stir in onion, chiles, 1/4 cup lime juice, and 1 1/4 teaspoons salt, then fold in pomegranate seeds, mango, and cilantro. Season with salt and additional lime juice. Garnish with lime wedges.
