Grease the spring plate (approx. 30 cm Ø) or spring form (28 cm Ø). Wash and clean the strawberries and, depending on size, cut them in half or quarters.
Whisk butter, 150 g sugar, vanillin sugar, lemon zest and 1 pinch of salt for 4-5 minutes until creamy. Stir in the eggs one after the other. Mix flour, starch and baking powder and stir in portions briefly.
Spread the dough into the spring sheet. Spread strawberries on top. Sprinkle with pine nuts and about 3 tbsp. sugar. Bake in the preheated oven (electric cooker: 175 °C/circulating air: 150 °C/gas: level 2) for 45-60 minutes (if necessary, cover shortly before the end of the baking time).
Allow to cool in the mould. Whipped cream tastes good with it.
