Knead 125 g butter in flakes, icing sugar, 250 g flour, 1 egg, lemon zest and salt to a smooth dough. Wrap in foil and chill for about 30 minutes. Roll out the dough on a work surface sprinkled with flour until round (approx. 30 cm Ø). Line a greased tart dish (26 cm Ø) with Lift off base. Press the rim lightly.
Prick the base several times with a fork and chill for about 30 minutes. Then bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for approx. 20 minutes. Let it cool down and take it out of the tin. Bring milk and sugar to the boil. Stir 2 eggs, 2 tablespoons of flour and starch until smooth. As soon as the milk boils, remove the pan from the heat and fold in the egg and flour mixture vigorously with a whisk. Bring to the boil again and simmer for about 5 minutes, stirring constantly. Remove from the heat, stir in 1 tablespoon butter and vanilla flavouring. If necessary, pass the milk cream through a sieve and pour onto the base. Dust generously with cinnamon.
