Grapefruit brulee in the oven
Theoretically, grapefruit brulee is a dish that only requires two ingredients. You could get away with just sugar and grapefruit, sure, but there's an untapped complexity if you're just sticking to those two guys.
I think it's important - especially with an ingredient as bitter as grapefruit - to create a balance among the flavors. For me, that's adding salt and a few spices.
If you like fire as much as I do, you're welcome to whip out a torch to hand-brown your grapefruit, but a broiler is pretty effective, too.
This recipe creates 4 servings of grapefruit.
What you need
1/2 cup sugar, preferably Turbinado
1/4 tsp salt
1/4 tsp ground cardamom
1/4 tsp ground cinnamon
How to do it
In a small bowl, combine sugar, salt and spices, and mix together by hand or with a fork.
Half grapefruits on a cutting board, then sprinkle sugar mix evenly over each grapefruit half.
Place grapefruit halves on a baking sheet covered in tin foil (you will regret it if you don't use tin foil).
Turn oven onto a high-broil setting, add baking sheet of grapefruit halves, and cook for 5-7 minutes or until the sugar has melted and turned a deep caramel color.
Remove grapefruit halves from the oven and serve immediately. Honeyed yogurt makes an awesome accompaniment.
This should not be made ahead of time and doesn't do well if stored and refrigerated - the sugar gets all gooey and melty and not crisp. This is best done a la minute.
