FOR THE MEATBALLS
Combine the bread crumbs and heavy cream in a small bowl, stirring with a fork until all the crumbs are moistened. Set aside.
Heat the oil in a small skillet over medium heat. Add the onion and saute for about 5 minutes, until softened. Remove from the heat.
In a large bowl, combine the ground beef, veal, pork, onion, honey, and egg, and mix well with your hands. Season with salt and pepper to taste.
Add the bread crumb-cream mixture and mix well. With wet hands (to keep the mixture from sticking) shape the mixture into meatballs the size of a golf ball, placing them on a plate lightly moistened with water. You should have about 24 meatballs.
Melt the butter in a large skillet over medium high heat. Add the meatballs, in batches if necessary, and cook, turning frequently, for about 7 minutes, until browned on all sides and cooked through. Transfer the meatballs to a plate, and discard all but 1 tablespoon of fat from the skillet.
FOR THE SAUCE
Return the skillet to the heat, whisk in the stock, cream, preserves, and pickle juice, and bring to a simmer. Season to taste with salt and pepper.
Add the meatballs to the sauce, reduce the heat to medium, and simmer for about 5 minutes, until the sauce thickens slightly and the meatballs are heated through. Serve hot with mashed potatoes, preserves, and Quick Picked Cucumbers.
FOR THE QUICK PICKLED CUCUMBERS (makes 1 1/2 cups)
Slice the cucumber as thin as possible (use a mandoline or other vegetable slicer if you have one. Put the slices in a colander, toss them with the salt, and let stand for about 30 minutes.
Meanwhile, combine the water, vinegar, sugar, bay leaf, and allspice in a medium saucepan and bring to a boil. Remove from heat and let cool.
Rinse the salt off the cucumbers, and squeeze out as much moisture as possible. Put the cucumbers in a medium bowl and add the pickling solution; they should be completely covered by the brine. Cover and refrigerate for 3 to 6 hours before serving.
