1. You can use plain flour instead of whole wheat flour. But as it said this is healthy bread I will not recommend it for making bread.
2. You can skip taking clarified butter and cook it as normal bread. This can aid you to lose some pound followed on a healthy diet. It is rich in protein, calcium and vitamin C which are the great nutrients for a healthy diet. I prefer it to make without butter and eat with plain yogurt. You can sprinkle some salt and black pepper powder on yogurt. Believe me, it tastes awesome and diet conscious people will like the bread and yogurt combo.
3. Storing: Dough keeps in the refrigerator for around 4 days. Tip: Roll out the rounds, ready to cook. Just make sure you use baking paper or cling wrap to keep the pieces separated, flour will not suffice.
4. Dairy free: It will also work substituting the butter with olive oil or coconut oil and make it a dairy-free version.
