Sprinkle the baking tray with 1 tablespoon of oil. Place baking paper on top and press down. Preheat the oven in the preheated oven (electric cooker: 200 °C/ circulating air: 175 °C/ gas: level 3) for 5-7 minutes. Mix eggs, milk, mineral water, 1 tablespoon of oil and flour to a smooth dough. Season with salt.
Pour the dough onto the hot baking tray and bake at the same temperature on the lower rack for 10-12 minutes until golden brown. In the meantime, wash the cabbage, cut out the stalk and hard leaf veins. Wash the orange, cut in half and squeeze out one half. Mix sour cream and mayonnaise. Season to taste with orange juice, salt, pepper and a little sugar. Take the crêpe out of the oven and let it cool down on a cake rack. Spread the crêpe with the cream, cover with cabbage and smoked salmon. Roll up the crêpe firmly. Cut the rest of the orange into slices.
