Chocolate & ginger refrigerator squares

I was looking for a dessert that required no cooking to make on holiday last week. Lazy I know, but holiday cooking should be easy. This was just perfect, everyone loves chocolate and with the use of a food processor it was made and in the fridge in 10 minutes. This recipe is also from the Goodfood website. 

Ingredients
300g ginger nut biscuits, roughly crushed
140g crystallised stem ginger, finely chopped
300g plain chocolate
100g butter, diced
100g golden syrup

Method
Line a 20 x 30cm tin with baking parchment. Mix the biscuits with most of the ginger, then set aside. Melt the chocolate, butter and golden syrup in a bowl set over a pan of simmering water, stirring occasionally, until smooth and glossy. Pour this over the biscuit and ginger mixture and mix together well.
Tip the mixture into the prepared tin and sprinkle over the reserved ginger, then flatten the top lightly – it doesn’t need to be completely smooth. Chill for at least 2 hrs, or overnight, before cutting into small squares.
