I'm sure you can make these just on their own, but if you've gone to the trouble of boiling them in Rapadura or sugar, you may as well make syrup with the bit you pour off, then make this delicious snack.
Ingredients
250g Hazelnuts, lightly crushed, without skin
500g Rapadura
500g Water
Instructions
Prepare as for Hazelnut Syrup.
Once you filter to separate the syrup and nuts, put the syrup aside to cool.
Spread the Hazelnuts over a baking tray
Place in the oven at 90C /194F for 3- 4 hours until they are beautifully crystalised and crunchy and golden in colour.
Use a spatula or spoon to move them around every half hour or so to make sure they don't burn.
