Excellent easy recipe adapted from Ninfa's restaurant.
Countertop space dictates every move in a compact kitchen, meaning any technique requiring a single saucepan and a standard countertop blender immediately earns its keep. Blending raw avocados directly with boiled vegetables creates an emulsion where the fruit's natural fats stabilize the purée, provided the cooked components are not boiling hot when they hit the blades. Letting the boiled jalapeños, garlic, tomatoes, and tomatillos cool for ten minutes prevents steam pressure from blowing the blender lid off.
Achieving a velvety consistency requires running the motor continuously for 45 seconds rather than pulsing, which ensures the fibrous cilantro leaves break down completely. Sour cream introduces dairy solids that separate if frozen, so keep this condiment strictly refrigerated rather than trying to preserve it in the freezer. Consume the mixture within 3 days to maintain vibrant green coloration before oxidation turns the avocado slate gray.
