Preheat oven to 220°C
First, prepare the Sticky Soy Glaze: Mix 1 tsp cornstarch and 2 tsp cold water together and set aside.
Place remaining sauce ingredients into a small saucepan and bring to a boil. Turn to simmer for 30 seconds. Next, whisk in the cornstarch and simmer a further 30 seconds, stirring continually until thickened. Remove from heat and leave to rest while you prepare the meatballs.
Combine meatball ingredients in a large bowl and gently mix together. Form into small-medium balls and place on an oven tray lined with baking paper. Roast for 10 minutes, turning once.
Whilst meatballs are cooking use a sieve to strain sticky soy glaze, rubbing ingredients into the sieve with the back of a spoon. You should now have a nice smooth sauce.
Return sauce to a medium heated pan and when bubbling, add meatballs. Toss until each ball is coated thickly with sauce.
Finish by sprinkling balls with sesame seeds.
