Sugary Grapefruit

Lately with this cold season, it's good to get your vitamins and citrus in. I love grapefruit, but sometimes it's just a little too much tartness. So I add sugar and toast it in my toaster oven (until i start to hear the juices come up. Maybe 3 minutes) and wow, it really brings the juices out as well as tone down the taste. Also it's warm so it makes for a good warm snack during the cold weather.
Note: Sometimes I also use brown sugar just to mix it up...but either or is really good.
