Whisk together 2 tablespoons sundried tomato water with 2 tablespoons melted butter and 1 tablespoon flour to form a loose batter. Heat a non-stick skillet over medium-low heat for about a minute. Drop 1 teaspoon of batter onto hot skillet. Be careful of splashing. Cook batter until it starts to firm up. As the water evaporates, the holes form. Carefully remove tuiles from pan with a spatula and drain on paper towel to cool.
