When I first make my guacamole, it often tastes too strongly of fruitiness (from the limes), salt, or garlic. Any/all of those seem to mellow out after a few hours in the fridge.

For context, here's my recipe: 5 avocados, 3-4 limes, ~1 tsp of minced garlic, 1 tomato, a few dashes of cayenne, and salt (to taste).
