On your working top put the flour, the egg, the sugar, vanilla extract and salt and stir the ingredients in well
Add the cold diced butter and with a fork mix it in well with the other ingredients.
Then working with your hands combine the ingredients well together and make them into a ball. If it feels sticky on your hands put it in the fridge for 30 minutes wrapped in cling film. Then flatten the pastry with a rolling pin
Lay the pastry on a round baking tray and pinch it all over with a fork
Spread a tbsp of jam all over the bottom of the tart
Peel and finally slice the apples, mix them up with a a tbsp of lemon and a tbsp of sugar and lay them nicely onto the pastry
Now spread the flaked almonds all over the apples and cook the tart at 200C for 25-30 minutes until the pastry at the edge looks nice and golden.
Make the gelatin and pour it over the apples. Let it rest until the gelatin has settled and cooled down before serving.
