Bring the wine and honey to a boil, then reduce the heat and skim off the foam until the liquid is clear. Add the vinegar, poudre forte, and fruits; return the mixture to a boil, then reduce the heat to a low simmer. Keep an eye on the fruit as you proceed—do not overreduce it! The syrup should lightly coat the back of a spoon and reduce by about a third to a half. Roll the sweet dough to about 1/4-inch thickness on a floured board, then use a circular cutter or drinking glass to cut out circles about 2 inches in diameter. Pour a shallow layer of oil into a skillet or pan and place it over medium-high heat until hot. Working a few at a time, gently slip dough circles into the oil and fry until they are lightly browned and very crisp. Transfer the fried circles to paper towels to drain. Arrange the cakes on a serving platter, then spoon on just enough of the fruit mixture to cover each disk. Sprinkle with candied nuts. The yellowish cakes and the red topping make an interesting contrast in colors, and the wine will soften the cakes.
