For best flavor and color, use very ripe but still green avocados and add the lemon juice immediately after mashing to slow browning; if you prefer a thinner, pourable consistency for salad dressing, whisk in extra buttermilk a tablespoon at a time until it reaches your desired texture, and if you like more tang, you can swap some of the sour cream for plain Greek yogurt. Fresh herbs give the dip a brighter taste, but dried herbs work well in a pinch—just reduce the quantity slightly since dried herbs are more concentrated. Store leftovers in an airtight container with plastic wrap pressed directly on the surface in the refrigerator for up to 2 days, and stir before serving as it may thicken slightly when chilled.
