Petits fours frais fall into three basic groups:
- miniature reproductions of specific cakes (miniature éclairs, duchesses, choux, tartelettes, barquettes, and babas);
- iced or glazed petits fours (small geometric shapes made from génoise or other cakes filled with buttercream, ganache, pastry cream, or jam, glazed and then iced, coated with chocolate, or coated with fondant and decorated with piped icing); and
- sugar-coated fruits, crystallized citrus rinds, or glazed fruits.
All of these have a very short shelf life and should be served as soon as possible after being prepared.
