Classic Tetrazzini consists of strips of cooked chicken combined with cooked spaghetti and a Parmesan cream sauce spiked with sherry. The casserole is sprinkled with bread crumbs and baked until it is brown and bubbly.
Sherry is a fortified wine originally from the southern Spanish town of Jerez. Fortified wines get their sweetness and strength from a dose of brandy or another spirit.
