1. Prepare a puree with the celery. The puree should be thick and dry, if it is too liquid, add an egg yolk.
2. Sauté carrot and zucchini slices in oil.
3. Line the bottom of 4 small tart molds with alternating vegetable slices (one carrot, one zucchini, one carrot...).
4. Spread the firmly packed celery puree on top.
5. Cut out 4 rounds of puff pastry and place them on the tart molds, on top of the puree.
6. Bake in a hot oven until the pastry is golden and puffed.
7. Serve hot with a green salad, or as a side dish with game. Enjoy your meal!
