Sadly, in the ingredients. Beignets, which are French fritters and were brought to Nola by its numerous French colonists, are traditionally made with choux pastry. Choux pastry, traditionally, is made of flour, water, eggs, and butter - making the beignets at locales like Cafe du Monde and Morning Call a non-starter for us vegan folk. **sadface**
But, aha! Local vegan restaurant Seed to the rescue! Thanks to this restaurant's tireless efforts to be the best thing ever in the world, local and traveling vegans alike can revel in the joy that is fried bread with sugar on it! This of course should not be everyday eating, but is a delightful occasional treat.
