How to Add Butter to Spiced Mashed Potatoes

"Hi my name is Allen Diwan and I'm the owner and chef of Kashmir Indian Restaurant in Budapest. We are here on behalf of Expert Village. The dish we are going to make is a spicy mashed potato with leeks. Then I'm going to use some mashed potatoes which have been boiled and mashed. We are going to put that in next fry. Mix it clearly and nicely into the leeks. Once it has taken in the spices and onion, we are going to add a little bit of butter. We are going to add a nice little dollop into it. The butter just uplifts the potato. The mashed potatoes are going to get a really nice flavor now from the butter."
