Japan loves to cook with liqueur. I think they believe alcohol is luxurious, which would explain the drinking culture here in Tokyo. Anyway, this orange custard is flavored with Cointreau and can curl your toes while you're making it if you get too close after heating.
It was also a test of my knife skills. Have you ever cut a half an orange into twelve slices? I have and nearly got myself a few times, even with safe knife precautions. A task for a mandolin? Are they sharp enough to cut oranges?
