375g pack Jus-Rol Sweet Dessert Pastry (or make your own!)
Roll out the pastry on a floured surface and use to line a 23cm fluted tart tin. Place in the fridge for at least 30 minutes to chill. Preheat oven to 200˚C, gas mark 6 with a flat baking sheet on the middle shelf.
Place the almonds in a food processor with the golden caster sugar and blitz until the mixture resembles fine breadcrumbs. Add the butter, eggs, plain flour and the Amaretto liqueur. Blitz until combined.
Remove the lined tart tin from the fridge,then spread the base with a thin layer of the marmalade, followed by the almond mixture. Scatter the blueberries evenly on top before placing in the oven on the preheated baking sheet to bake for 10 mintues.
Reduce the oven to 180C, gas mark 4 for a further 30 minutes and cook until golden and crisp.
