No, If you only have butter, you can clarify it first before using it. Put the butter in a saucepan over high heat. Once the butter is fully melted, leave it to boil for few minutes until the bubbly foam disappears. Pour it into a bowl and let it cool down. Once cooled, the clarified butter will be on the top and the milk solids on the bottom. Use only the yellow clarified butter on the top.
