Fans of acidity adore him, ever since he tumbled down Rue de Sèvres. Laurent Boughaba, the grandson of an arborist, pampers 250 varieties of citrus on his Moroccan orchard, which he then exports to Paris and sells at his boutique specialized in citrus of all kinds. That’s where you can unearth, much like Pascal Barbot (Astrance) and Alain Passard (Arpège), limonettes from Marrakech, tangelolos (a combination of Tangier tangerines and pomelos), Corsican citrons and Washington oranges. Other options, lined up on the immaculate shelves: an artisanal orange and Timur peppercorn syrup, pink lemon and hibiscus marshmallows, yuzu and Maltese orange jam… Get a dose of sunshine to jumpstart your life! // Albert Gredinbar

The hidden gem: The dekopon (a type of Japanese orange), whose peel is candied and stuffed with a frozen filling, prepared by the Meilleur Ouvrier de France pastry chef Emmanuel Ryon (€16).
