Note 1. Place a medium sized heavy bottomed fry pan over medium/medium high heat, and add 1 teaspoon sesame oil, 1 teaspoon caper juice to the pan. When the pan is hot, add the tuna steaks and 2-3 teaspoons of the minced beetroot. Cook on each side for about 3-4 minutes [depending on the size of the tuna steaks] - you want the steaks to be rare/medium rare. DO NOT OVERCOOK!! Remove from the pan to cool, before serving.
