Grease a ring cake tin (approx. 2 l capacity) and dust with flour. Preheat the oven: (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3). Pour yoghurt into a bowl. Wash and dry the cup and use it as a measuring cup.
Finely chop the pistachios. Cream butter, sugar and 1 pinch of salt with the whisk of the hand mixer. Stir in the eggs one by one. Stir in yoghurt. Mix the pistachios, up to 2 tbsp., with flour and baking powder, stir in briefly.
Fill the dough into the mould and smooth it down. Bake in a hot oven for 45-50 minutes. Let the cake cool down in the tin for about 15 minutes. Then turn over and prick several times with a wooden skewer.
Boil up lemon juice and honey. Sprinkle the hot ring cake with the lemon juice and honey and sprinkle with the remaining pistachios.
