Harry Potter Grape Tart Recipe Ingredients

(serves 6-8)


For the shortcrust pastry recipe

  • 150g plain flour

  • pinch of salt

  • 75g butter

  • 50g icing sugar

  • 1 egg yolk

  • 1-2 tbsp cold water

For the maple cinnamon grape pie filling recipe

  • 1 punnet of grapes (approx. 500g)

  • 2 tbsp maple syrup

  • ¼ tsp cinnamon

  • 50g soft brown sugar

For the diplomat cream recipe

  • 300ml milk

  • 2 tbsp golden caster sugar

  • 1 tbsp cornflour

  • 2 egg yolks

  • 1 egg

  • 1 tsp vanilla extract

  • 150ml double cream

Homemade Grape Tart Recipe Method:

  1. To make the homemade shortcrust pastry recipe start by placing the flour into a bowl with the salt and stir together. Add in the room temperature butter and work with your fingers until it forms breadcrumbs. Stir through the icing sugar and then make a well in the middle.

  2. Add the egg yolk and water into the middle and then use a knife to bind it together. Use your hands to form a smooth ball of dough and then wrap in cling film before placing in the fridge to chill for 15 minutes. (Wizard Tip! The trick to pastry is to not over work it so as soon as it's come together, even if it's a little soft, chilling in the fridge will firm it up so you can roll it more easily)

  3. Lightly flour your worktop and roll the pastry out to ½ cm thick. Lift the pastry up using your rolling pin and transfer into your tart tin, working it into the sides and bottom. Prick the bottom with a fork to prevent it rising. Cover the pastry with baking paper and then fill with baking beans. Bake at 180c (350F) for 10 minutes.

  4. Remove the baking beans and baking paper, trim down the sides to neaten the edges and then bake for another 10 minutes.

  5. Prepare the grapes by washing them, cutting in half and placing on a baking tray. Drizzle over the maple syrup and cinnamon and then gently roast in the oven 140c (280F) for 15-20 minutes until they have caramalised.

  6. To make the diplomat cream recipe, start by creating an easy homemade creme patisserie. Gently warm the milk in a pan being careful not to burn it. In a separate bowl add in the sugar, cornflour, egg yolks, egg and vanilla and then whisk into a smooth paste.

  7. Once the mixture is light and foamy, slowly pour in the hot milk whisking continuously to prevent any lumps forming. Once all the milk is incorporated, transfer back into the pan and heat for about 2-3 minutes, stirring continuously while it thickens. Transfer into a bowl, cover with cling film to prevent a skin forming and allow to cool.

  8. For the grape jam filling, place a saucepan on a medium heat and add in half your caramalised grapes along with the sugar. Bring the mixture to the boil, breaking the grapes up as your stir. After 5 minutes transfer to a food processor and blend into your jam. Spread this over the bottom of the tart tin.

  9. To finish the diplomat cream, pour the cream into a bowl and whisk until it forms stiff peaks. Gently fold half the whipped cream into the cream patisserie being careful not to knock out too much air. Once even, fold in the remaining half of cream. Transfer into a piping back to help evenly distribute over the top of the grape filling.

  10. Use the remaining grapes to decorate the top of your tart. I used red grapes as the lightning bolt and white grapes around the outside to help it stand out. Place the finished tart into the fridge for 30 minutes to firm up.

I guess Colin's journey to the hospital wing wasn't in vain after all!
