Finely grind the walnuts. Mix with flour and sugar. Add egg yolk, approx. 2 tbsp. cold water and butter in pieces. Knead first with the dough hooks of the hand mixer, then briefly with your hands until smooth. In a greased pie or tart tin (approx. 26 cm Ø), press until smooth and pull up slightly at the edge. Prick the base more often with a fork. Cover and chill for approx. 30 minutes.
Place a large piece of baking paper on the dough. Fill with legumes. Pre-bake in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 15 minutes. Remove baking parchment together with the pulses. Bake the tart for about 10 minutes more. Cool down
Stir cream cheese, icing sugar and orange juice until smooth. Spread on the tart base until smooth. Heat the jam and pass through a sieve. Spread half on the cream. Chill for about 1 hour.
Peel and slice the kiwis. Cover the tart with them. Heat the rest of the jam again and spread on the kiwis. Sprinkle with walnuts
