If making your Blueberry topping using this recipe, do that first, then set aside to cool.
In a frying pan over low heat, toast the hazelnut meal. Keep stirring or tossing for a few minutes just until it's looking more golden in colour.
Add the ground hazelnuts, flour, sugar and salt to a food processor and blitz until well combined.
Add the butter and blitz for only 5-10 seconds until the mixture is like large breadcrumbs.
Slowly drizzle in the water while the processor is running on low and stop as soon as it starts forming large clumps.
Tip the dough out onto a piece of baking paper and use the paper to help you pull it together into a flat disk. Wrap in the baking paper and place in the fridge for 45 minutes.
Preheat the oven to 180C / 350F / 160C fan forced. Grease the holes of a 12 hole muffin tin
Roll out the pastry between 2 sheets of lightly floured baking paper to about 4mm / 1/6 inch thick. Use a large round cookie cutter to cut out circles from the pastry. Check the first to make sure it fits into the muffin tin hole and reaches the top.
Gently push each circle into the hole of a 12 hole muffin tin. Chill for 10 minutes. Spoon in the blueberry filling to about 3/4 full.
If using, top the pies with more pie dough. If you cover the whole top, make sure to cut at least a small hole or cross in the top for steam to escape.
Bake for 25-30 minutes until they look golden and crisp. Let them cool a little before dusting with icing / powdered sugar to serve.
Recommended equipment: food processor, 12 hole muffin tin
I use a standard Australian 20ml tablespoon (= 4 teaspoons worldwide)
All ovens vary – always test for doneness 3-5 minutes before the recipe suggests
For best results, you should always weigh ingredients like flour and sugar. Kitchen scales are relatively cheap but if you can’t weigh the ingredients, use the spoon and level method (don’t scoop).
Hazelnuts: You can use already ground hazelnuts, also known as hazelnut meal, or you can use whole hazelnut kernels and grind them in the food processor.
