For extra smokiness, roast the eggplants over a grill or directly on a gas burner before finishing in the oven. Storage: Refrigerate in an airtight container up to 5 days. The dip may thicken after chilling—stir and add a drizzle of olive oil or a squeeze of lemon to loosen. Freezing is possible up to 3 months, but texture can turn slightly grainy; thaw in the fridge and re-blend if needed.
