Makes 15-20 slices

75g/3oz soft brown sugar
75g/3oz unsalted butter
A pinch of salt
1 tbsp golden syrup
2 tbsp chopped walnuts
100g/3 oz raisins, roughly chopped
175g/6oz oats

Pre-heat the oven to 180C/350F/Gas4.

Put the sugar, butter, salt and golden syrup into a saucepan large enough to comfortably hold all the ingredients. Place over a gentle heat and cook just until the sugar has dissolved.

Add the walnuts and raisins. Stir in the oats, and pour into a 20cm baking tray. Press down firmly with your hand, and place on the middle shelf of the oven.

Bake for 20 minutes then remove and cool on a wire rack. Once at room temperature, slice into small squares and serve.
