Turn and cook 15 artichokes in the white court-bouillon, then set aside. Wash and drain the mesclun salad greens.
Turn the remaining 3 artichokes raw, retaining the hay and inner leaves. Slice the bases thinly on a mandoline, then cut into julienne. Lightly dress with lemon juice and refrigerate, covered.
Cut the raw foie gras into small cutlets; pan-fry just before serving.
Slice the cooked artichoke bottoms to 3 mm thickness on a mandoline. Cut into 33 mm rounds using a cookie cutter (yielding 90 slices). Sauté in butter and season to taste.
Vanilla Verjuice Syrup: Combine verjuice, sugar, split and scraped vanilla pod, mignonette pepper, and rosemary. Bring to a gentle boil, skim, and infuse. Reduce heat, add sliced turnips, and cook slowly until tender.
Truffle Vinaigrette: Whisk together in order: salt, balsamic and truffle vinegars, truffle oil, and pepper. Set aside.
Assembly: Slice cooked turnips and semi-cooked foie gras to match the artichoke rounds. Stack in layers—artichoke, foie gras, turnip—repeating twice for three layers per tower. Press gently to set.
Finishing & Plating: Arrange 5 towers (Tendresses) per plate. Top each with a pan-fried raw foie gras cutlet, a chervil sprig, and a pinch of Guérande salt. Mound mesclun in the center.
Sauté artichoke julienne briefly in browned butter. Scatter over the plate with truffle julienne and drizzle with truffle vinaigrette.
Pro Tip: Source specialty ingredients from gourmet grocers. For ease, use high-quality frozen artichoke bottoms, such as those from Picard. Bon appétit—this refined dish showcases classic French technique with luxurious flavors.
