Heat honey, sugar and 30 g butter in a pot while stirring (do not boil) until the sugar is dissolved. Leave to cool down to approx. 40 °C.
Wash, clean, peel and quarter the pears and cut out the core. Cut the pear quarters lengthwise in half or in thirds.
Caramelise icing sugar and 4 tbsp. water in an ovenproof pan or mould (approx. 24 cm Ø, 4-5 cm high) until golden brown. Add 80 g butter and pears and steam for 8-10 minutes, turning occasionally.
Let it cool down for 10-15 minutes.
Mix flour, spices and baking powder and sieve into a bowl. Add egg and honey mixture. Knead to a smooth dough with the dough hooks of the hand mixer. Roll out the dough on a floured work surface to a circle of approx. 26 cm Ø, place it on the pears.
Carefully press the protruding edges of the dough downwards into the mould.
Bake in the preheated oven on the 2nd rack from below (electric oven: 175 °C/ circulating air: 150 °C/ gas: see manufacturer) for approx. 25 minutes. Leave the finished Tarte Tatin to cool in the mould for about 5 minutes, then turn out of the mould directly onto a plate.
Dust with icing sugar as desired. Vanilla ice cream tastes good with it.
