Cut chicken into bite sized pieces and dust with corn starch.
Brown the chicken over high heat, in batches if needed. Reserve.
Prepare aromatics while waiting for chicken to brown. Once chicken is done, turn the heat down and fry the ginger until fragrant.
Add whole garlic cloves and sauté over gentle heat, until softened and browned.
Add sugar into the pan, heating until it’s dissolved into caramel. Add chicken back to pan and toss to coat.
Add the sauce, stirring to combine. Simmer for a few minutes until thickened. Taste and adjust seasoning.
Turn the heat off and stir in Thai basil, letting them wilt in the residual heat.
Serve, ideally by spooning it onto rice along with plenty of the sauce.
