Glace Des Medoc:
Melt 3 tablespoons butter in a medium saucepan. Add shallots and saute until beginning to brown. Add wine and stir to deglaze the pan. Cook until wine is reduced to a syrup. Add veal stock and reduce until sauce consistency. Add butter, 1 piece at a time, and swirl to combine. Keep warm.
Melt oil and butter in a large skillet over medium-high heat. Season ostrich with salt and pepper. When pan is hot, add ostrich and sear on both sides until cooked to a medium doneness; it will not take long, as ostrich cooks very quickly and is not good when over-cooked. Reserve and keep warm. It may be necessary to sear the ostrich in 2 batches, so as not to over-crowd the pan.
To serve, layer potatoes with spinach and tomatoes in a 2-inch ring mold. Place a pretty oval of potato on top with another dried tomato. Spoon a thin line of salsify puree onto the plate. Slice the ostrich on a sharp bias and place it next to the potato stack. Garnish with sweetbreads, asparagus, and enoki mushrooms. Drizzle Medoc reduction around the plate.
