Canapé bases may be made from several items. Suggestions include:
Bread cutouts
Toast cutouts
Crackers
Melba toasts
Tiny unsweetened pastry shells (short dough, phyllo dough, or other pastry)
Profiteroles (miniature unsweetened cream puff shells
Toasted pita wedges
Tortilla chips or cups
Tiny biscuits, split in half if necessary
Polenta cutouts
Miniature pancakes
Many of these items, such as crackers and Melba toasts, can be purchased ready-made, but bread and toast cutouts are the most widely used and offer the lowest food cost, though they require more labor.
