Schaum aus Meeres-Erizos

Espuma de erizos de mar or sea urchin foam is a traditional tapa that's believed to be the most exquisite of them all. It's made with a combination of sea urchins, egg yolks, pink cava or sparkling rose, cream, and salt. The egg yolks and cava are whisked until the mixture becomes foamy and thickens. The sea urchin roe (uni) and cream are beaten until foamy, and it's then mixed with the egg yolk and cava mixture. The warm mixture is spooned into cleaned sea urchin shells and served on a bed of salt. This tapa is eaten with a teaspoon.
