Put flour, 150 g butter in flakes, salt, 75 g sugar, 1 egg and 1 tablespoon cold water in a bowl. Knead first with the dough hooks of the hand mixer, then with your hands to a smooth short pastry.
Wrap dough in foil and chill for about 30 minutes.
Roll out the short pastry rectangularly (approx. 22 x 30 cm) on a floured work surface. Place the dough in a greased tart mould (20 x 28 cm) with a lift-off base, dust with flour and press down.
Prick the dough several times with a fork, place baking paper on top and add dried peas.
Pre-bake the tart on the lower shelf in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 25 minutes. Take the tart out of the oven, remove peas and baking paper and let it cool down on a cake rack.
Mix 175 g soft butter, honey, almonds, cloves and 3 eggs well together. Stir in cream. Wash, clean, drain and halve the nectarines. Remove seeds, dice flesh.
Spread the almond paste on the shortcrust pastry, spread nectarines on top and bake in a preheated oven at the same temperature for another 30 minutes. Remove and let cool on a cake rack.
Carefully lift out of the mould, place on a cake plate and dust with icing sugar.
