Hazelnut Frangelico

2. After two weeks, strain the vodka, pressing the nuts with a wooden spoon or spatula to release their flavour. Discard the nuts. Strain the liquid again through a coffee filter or fine muslin.

3. Bring the sugar and water to a boil in a small pan and simmer for five minutes until syrupy. Cool, then add the vanilla pod (bash it first with the handle of your knife to release the flavour); if you are dividing the syrup between two half-bottles, cut the vanilla pod in half.

4. Add the syrup and vanilla to the hazelnut liqueur. Transfer to a bottle or bottles and store for four weeks before drinking, turning occasionally.
