Sweet and sour is a classic combination of flavors that can be found in almost every cuisine around the world, and in Italy it's called agrodolce and produces delicious, balanced dishes of savory and sweet. Lidia demonstrates a marinated winter squash: fried and soaked in a sweet and tangy marinade made from vinegar, garlic and sugar; swordfish in sweet and sour sauce, showcasing a perfect balance between sweetness and acidity in each bite; sesame candy: a flavor packed sesame candy with citrus zest.
