My favourite bit of the Foire de Paris - the syrup tree. Moulin de Valdonne make the posh syrups and cordials that go into cocktails, and that also make nice recipe ingredients. And you can just have it like cordial. Help yourself to syrup from the tree, and top up with water from the nearby coolers. Violette is pretty interesting, but not actually nice to drink. I bought a bottle of Recette Provencale (strawberry, cantaloupe, lemon and watermelon), which is very nice.
