In a mixing bowl, stir together all the meatball ingredients.
Cover and refrigerate for 20 minutes. Meanwhile, bring a large pot of water to a gentle simmer over medium-low heat.
Form the mixture into meatballs and lower them directly into the simmering water as you work. Poach for 5–7 minutes, or until cooked through. While they cook, whisk the sauce ingredients together in a bowl.
Heat a skillet over medium-high heat and brown the drained meatballs on all sides.
Pour in the sauce and simmer, stirring occasionally, until it thickens and the meatballs are well coated.
Sprinkle with sesame seeds and serve.
Notes
Patience is keylet the sauce thicken so it clings to every meatball.
