Cocktail Meatballs

Make the Meatballs: Preheat the oven to 325°F (165°C). Line a baking sheet with aluminum foil for easy clean-up and place an ovenproof rack over top; spray the rack generously with nonstick cooking spray.

Whisk the egg and cream together in a medium bowl. Stir in the bread and mash with a fork until the bread is broken down. Set aside.

In a stand mixer fitted with the paddle attachment, beat the pork, garlic, pepper, salt, and baking powder on high speed until smooth and pale, about 2 minutes, scraping bowl as necessary. Add the bread mixture to the mixing bowl and beat on high speed until smooth and homogeneous, about 1 minute, scraping the bowl as necessary. Add the beef and mix on medium-low speed until just incorporated, about 20 seconds, scraping the bowl as necessary.

Using wet hands, form the mixture into 1½-in (4-cm) round meatballs and place on the prepared rack. (The mixture is very sticky; wet hands help, so keep wetting your hands as you go). Bake for about 25 minutes, until just done. (Note: You'll notice that the rack will leave little marks on the bottom of the meatballs but they will not be too noticeable once the meatballs are covered with sauce.)

Make the Sauce: Meanwhile, in a large skillet, whisk together the ketchup, brown sugar, water, cider vinegar, Worcestershire sauce, shallot, garlic, salt, and pepper. Bring to a boil, then reduce the heat and simmer until thickened, 10 to 12 minutes.

Add the baked meatballs to the sauce and simmer until warmed through. Transfer the meatballs to a serving platter, spear with toothpicks, and spoon the sauce over top. Garnish with parsley, if using. Serve warm.
