Roll out the base on a piece of baking paper (with a damp cloth underneath) to a circle (approx. 31 cm Ø). Then place it in a greased tart tin (28 cm Ø) sprinkled with flour, lightly press the base and rim and prick several times with a fork. Chill for about 30 minutes. Then line the base with baking paper and fill with dried peas up to the rim. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) on the lower shelf for approx. 25 minutes.
Remove from the oven, carefully remove the dried peas and baking paper. Bake at the same temperature for another 12 minutes. Remove and let cool on a cake rack. Then remove from the tin. Defrost the peas at room temperature for the filling. Wash the herbs and shake dry. Cut chives into fine rolls. Finely chop parsley and dill. Soak gelatine in cold water. Mix cream cheese and yoghurt with the whisk of the hand mixer. Season well with salt and pepper. Whip cream until stiff. Squeeze the gelatine and melt. Remove from the stove.
