Italiano Ingredient
Italian has three ways to express the presence of an ingredient in the name of a dish:
Dish di
ingredient
the ingredient is the main or only
component of the dish.
e.g. “succo di limone” (lemon juice).
In this case the article is never used before the ingredient.
Dish con
ingredient
the ingredient is a visible component
of the dish or used as garnish
e.g. “fragole con panna” (strawberries with cream).
In this case a definite article can be used before the ingredient.
Dish a
ingredient
the dish has been flavored
with the ingredient, or tastes like the ingredient
e.g. “gelato al cioccolato” (chocolate ice cream).
In this case the definite article is mandatory before the ingredient, forming an articulated preposition with a.
