M&S 4 Tiger Rolls Soft white rolls made with wheatflour and toped with a tiger paste for a mottled crust. Four per pack. All of our breads are a natural source of Vitamin D and Fibre, two nutrients that are naturally low in our diets. We use a natural source of Vitamin D that is produced by yeast, which is why you will find ‘yeast’ on our list of ingredients, not because we use it as part of the dough making process.
