Whether you’re celebrating Bastille Day or just want to experience a little joie de vivre, this French-inspired picnic menu makes the most of a glorious summer day. Start with crisp radishes dipped in a soft caraway-scented butter. As with most French dishes, it all depends on the quality of the ingredients, so splurging on a great, cultured butter makes all the difference. For the main course, tuck into a pan bagnat, a pressed sandwich from the south of France that is basically Niçoise salad on bread. It’s paired with a French-style potato salad, dressed in a tarragon vinaigrette in place of an American-style creamy dressing. Finish the meal with a mixed-berry slab pie, or jalousie if you want to be fancy and French about it.
