What is Leche de Tigre?

Danny, in the 'spoiler' for the Top Chef Wisconsin Finale, was heard to say that he wanted to get fresh scallops for his first course and treat them in the style of "Leche de Tigre".

Leche de tigre, (translates to tiger's milk), is the Peruvian term for a citrus marinade that cures fish or seafood. Also known as leche de pantera, this marinade usually contains lime juice, onion, chile, and fish sauce.
