Our turkey meatballs rival those made from beef or pork, thanks to a few test kitchen tricks. We start with 93 or 85 percent lean turkey; the 99 percent lean type didn’t have enough fat to create a palatable meatball. Next, we add an egg and fresh bread crumbs (instead of a panade, which made the meatballs too wet) to help bind the meat. We also add a small amount of unflavored gelatin, which mitigates graininess by trapping moisture and giving the meatballs a juicy mouthfeel. To boost meaty flavor, we add glutamate-rich ingredients such as Parmesan cheese, anchovies, and rehydrated dried shiitake mushrooms. These meatballs are also flavored with scallions, soy sauce, white pepper, and sesame oil.

Instructions
Prepare the mushrooms:
Microwave broth and mushrooms in covered bowl until steaming, about 1 minute.
Let sit until softened, about 5 minutes.
Drain mushrooms in fine-mesh strainer and reserve the liquid.
Prepare the bread crumbs:
Pulse the bread in a food processor until finely ground, 10 to 15 pulses; transfer the bread crumbs to a large bowl (do not wash processor bowl).
Add the Parmesan, scallion whites, half of the scallion greens, sugar, 1 ½ teaspoons of gelatin, 1 teaspoon of salt, and 1 teaspoon white pepper to the bowl with the bread crumbs and mix until thoroughly combined.
Make the meatballs:
Pulse the mushrooms and anchovies in the food processor until chopped fine, 10 to 15 pulses.
Add the mushroom mixture, turkey, and egg to bowl with the bread-crumb mixture and mix with your hands until thoroughly combined.
Divide the mixture into 16 portions using a #16 portion scoop, (about ¼ cup each).
Using your hands, roll each portion into ball.
Transfer the meatballs to a plate and refrigerate for 15 minutes.
Prepare the gelatin and brown the meatballs:
Sprinkle remaining 1 teaspoon gelatin over water in a bowl and let stand until the gelatin softens, about 5 minutes.
Heat vegetable oil in a 12-inch nonstick skillet over medium-high heat until shimmering.
Add the meatballs and cook until well browned all over, 5 to 7 minutes.
Transfer the meatballs to a paper towel–lined plate, leaving the fat in the skillet.
Make the sauce:
Add garlic to the skillet and cook, stirring constantly, until fragrant, about 30 seconds.
Increase the heat to high, stir in the soy sauce, sesame oil, reserved mushroom liquid, gelatin mixture, and remaining ½ teaspoon of white pepper and bring to a simmer.
Finish and serve:
Return the meatballs to the skillet, reduce the heat to medium-low, cover, and cook until meatballs register 160 degrees, 12 to 15 minutes, turning the meatballs once.
Transfer the meatballs to a platter.
Season the sauce with salt to taste, pour over the meatballs, garnish with remaining scallion greens, and serve.
