Just a note worth mentioning.
I'd bought these things before and never been too impressed with them: they were less flavorful than pears, with most of the texture of an apple.
My mistake was in not peeling them: The peels are tough and bitter, adding nothing to the flavor. Unlike a plum, where the tartness balances the sweet flesh, or a pear where it's thin and mostly unnoticed (except for the wonderful rough texture of a bosc), get rid of these skins, and you've got a great fruit with a crispness you don't get from pears and a lot of flavor.
I'd used them at our xmas party in a Ming Tsai recipe, where they're julienned, tossed with black pepper and lime juice, then wrapped in proscuitto and sliced to appear as maki. Mmmmm. Don't use too much lime juice, or the proscuitto won't stick together.
What is patriotism, but the love of good things we ate in our childhood?
