Preheat oven to 170C. Heat the butter, sugar and syrup together in a pan till butter is melted. Sift flour into a bowl and add oats and ginger. Mix well. Pour the melted mixture in and mix in well. Roll small balls of the mixture in hands and place onto a greased baking sheet. Squish slightly with your fingers. They don't spread too much but give them a bit of space. Bake for around 10 minutes or until browned. Transfer to a wire rack and cool.
