Cut off the tops of six rolls, take out all the crumbs, fill them with a ready made [chocolate] cream, and cover them with the tops that were cut off, soak them in sweet Spanish wine, about a quarter of an hour; then wipe and flour them; fry of a good colour, and glaze them with sugar.

Here is the modern adaptation.
Let me just say that the chocolate custard is so fantastic by itself, I thought the wine-soaked, deep fried, sugar-strewn rolls took away from it. Yes, the chocolate is that good. Since I'm going to be making this over an open fire in as yet unknown weather conditions, I think I'm just going to stick to the custard.
Here are some of my amateur observations:
If you let the rolls sit out for a day, it's just about impossible to grate the crust off, at least with the microplane I have. Instead, I grated them and hollowed them out and then let them get good and stale.
I think soaking in wine is a bit of overkill and made them soggy. I just dipped them in a bowl of wine, and still thought they were too soggy. I would actually do this step first, and give them more time to drain, or I'd sprinkle them with wine and let it soak in slowly.
Deep frying in a saucepan (because all I'm going to have at the event is a spider) is not my strong point. Especially with cup-shaped, hollowed out rolls. And deep-frying in the rain doesn't sound like fun.
YMMV, but I think I'll just stick with the custard.
