Is dough pastry made with margarine or butter?

Dough pastry is usually made with butter, not margarine. Butter is made from milk fat and is solid at room temperature, whereas margarine is a dairy-free butter alternative made from vegetable oils and is usually solid at room temperature as well. Butter contains saturated fats and water, while margarine contains higher levels of unsaturated fat. Butter also has a higher smoke point than margarine, making it better for frying and searing.
