Place avocados in another bowl and mash with fork, slowly adding pomegranate juice. Fold in onion mixture, keeping texture coarse. Gently fold in pomegranate arils and serve immediately, or place avocado pits on top of guacamole to keep it from darkening, cover in plastic wrap and refrigerate until ready to serve.
Wine Suggestions: The buttery texture of the avocados paired with corn chips and a bit of spice call for a Chardonnay that is not too dry or too acidic. Try Tryptic Colombia Valley Chardonnay.
