Set a clean pot on fire, add in the oil, add two or three kernel in the oil and allow to pop, remove it and pour the remaining kernel in the pot, remove from the burner and set aside for 30secs. Put back on fire and allow it to pop, when you no longer hear the pop sound shake vigorously and set aside. In a pan, add the butter, sugar and vanilla flavor stir continuously to avoid burning, when it melts, pour it on the popcorn, add milk and shake for it to mix well. Enjoy
