I had forgotten how delicious this is. My Mom used to make this for me and I haven't had it in forever. Saw the grapefruit sitting there this morning and decided to give it a go for posterity. I think it's going to be a breakfast regular around here again.
It's so easy to make.
Chill a grapefruit
Cut it across the middle so that each segment is cut in half (not from top to bottom)
Use a serrated knife to cut around to loosen each segment (but leave them in the grapefruit)
Cover the top of the grapefruit with a spoonful of brown sugar and flatten the sugar out
Place under broiler until the sugar bubbles and caramelizes.
