The difference between a crostini and bruschetta has to do with the type of bread that is used and the way that is sliced. Bruschetta is made with toasted slices of bread that are cut wide. Often a Sourdough is used. Crostini is made by toasting smaller slices of bread like a baguette.  Bruschetta is usually topped with marinated toppings such as chopped fresh tomatoes, onions and basil. Crostini is topped with spreads such as jams, goat cheese, and tapenades. Technically you could consider this recipe a cross between a crostini and bruschetta since it uses a baguette like a crostini, and the marinated topping like bruschetta.
