In a small saucepan add sugar, corn syrup, butter and vinegar to a simmer. Remove from heat and pour into a large mixing bowl. Set aside to cool for 5-10 minutes.
Mix in egg. Sift together the flour, soda, pepper, ginger, cloves and cinnamon. Cover and refrigerate for several hours or overnight.
Once the dough has chilled, roll the dough very thin on a floured surface. Cut into any desired shapes. Bake at 350℉ on a parchment-lined baking sheet for 7-8 minutes. Remove cookies from the baking sheet immediately and allow to cool. Store in airtight tins.
Layer the Norwegian Christmas cookies in tins and store in a cool place. Pepperkaker will keep well for up to 3 weeks when kept in an airtight container.
