This refers to a versatile base, most commonly a slice of baguette, a cracker, or a small piece of toasted bread, designed to hold toppings. It's typically made from simple, neutral-flavored ingredients like refined or whole wheat flour, water, yeast, and salt. While the concept is universal, the classic crostini or canapé base is a staple of French and Italian appetizer cuisine.
The base itself is primarily a source of carbohydrates for quick energy, with a moderate amount of protein from the wheat. A single, small piece provides roughly 30-50 calories, making it a light vehicle for richer toppings.
