Remove the foil and paper. Spread approximately 100g of seasoned or sweetened sour cream (crème fraîche, Schmand) evenly over the tarte flambée base, leaving a 0.5cm border, and top with the desired ingredients. Depending on the toppings, the tarte flambée can be enjoyed in a variety of flavors. Whether savory, spicy, or sweet: anything goes, for example: with salmon and spring onions, with Gorgonzola and spinach, with soft cheese (feta), pepperoni and bell peppers, with mushrooms, bacon, and herbs de Provence, or with diced apple and cinnamon sugar (recommendation: flambé with Calvados after baking).
Baking instructions: The best baking results are achieved in a preheated oven with a firebrick or wire rack. Bake the tarte flambée (without parchment paper/foil) directly on the firebrick or granite stone for 4-6 minutes at 250-300°C (480-570°F) using top and bottom heat until crispy. Alternatively: Bake in a preheated convection oven (reduce the fan speed as much as possible) with a baking plate or coated baking tray at 250°C (480°F) for approximately 5-7 minutes.
