Sift flour on the table and press a well in the center. Add margarine, salt and water to the well, crumble the ingredients together and knead very quickly to form a dough. Let the dough rest in the refrigerator for half an hour.
Meanwhile, dice the zucchini and slice the tomatoes. Roughly chop the basil. Mix Rama Cremefine for cooking with the eggs, lemon juice, basil and garlic and season to taste.
Grease four tartlet molds Ø 15 cm. Roll out the dough, cut out four circles Ø 18 cm and place them in the mold. Press the dough down a bit and cut off the overhanging edge. Put the zucchini and shrimps in the molds and pour the cream over them. Finally, top with tomato slices and bake in a preheated oven at 200°C for 20 minutes.
