What mazamorra cordobesa is
Mazamorra cordobesa is a cold soup made from ground almonds, stale bread, garlic, olive oil, and water. No tomatoes. No peppers. Nothing from the Americas. That's the point — this dish existed before Columbus sailed, which makes it one of the oldest cold soups still served in Spain.
It's sometimes called 'white salmorejo' or 'white gazpacho,' though both comparisons slightly miss the mark. Mazamorra is its own thing: paler, subtler, and heavier on almond than any modern interpretation suggests. Served ice-cold in a shallow bowl, garnished with black olives, halved grapes, and diced boiled egg.
