This was my first attempt at this recipe. Next time I think I will substitute chives for the dill. I made it in the food processor, but a blender should work, too.
2 avocados (or 3 if you want to use the third for garnish)
½ small to medium Vidalia onion
2 cups buttermilk
1/3 cup fresh dill
1 tablespoon basalmic vinegar
1 teaspoon to one tablespoon garlic powder
Put everything in the food processor (except the 3rd avocado) and process until very smooth. Chill in the refrigerator for and hour. Top with diced avocado if desired.
I put in onion in and process it first so it won’t be chunky. This will probably turn brown, like guacamole, if you try to keep it very long.
