I found and modified this recipe from http://suburblicious.com . It's just what I was looking for to make a Chinese Week of cooking complete.
Cube the chicken and place in a bowl. Add the milk, sherry and salt and pepper, mix until coated, then place in fridge for 1 hour. Drain without drying.
Mix the flour and the baking powder, then coat the cubes liberally. (You may need more flour for this step)
Heat the olive oil in the non-stick frying pan, and saute the chicken over medium heat, rotating once during cooking. Cook until crusty and brown, but not burnt, then remove.
Pour the water in the skillet along with diluted corn starch, soy sauce, honey, rice vinegar, chipotle pepper and ginger. Bring to a quick boil and thicken the sauce. Add the sesame oil and test for taste, adding more soy sauce or pepper.
Finally, remix the chicken in with the sauce. If storing for a later date, skip this step, as chicken will get soggy.
Serve on a bed of jasmine rice, and decorate with roasted sesame seeds.
