Sea bass, grapes and ajo blanco

A great way to get something fancy on the table quickly, this dish feels smooth and ‘restauranty’, even though it takes just ten minutes. A chilled soup is a hard sell for a family, but when you present ajo blanco as a sauce, I find they will accept it. (And yes, I know usually it would not contain parsley, but I like it here.)

SERVES 4
