Lightly pound and tenderize the chicken thighs so they are more flattened. Be sure to have patted them dry.
Dust them LIGHTLY with thin layer of cornstarch or potato starch.
Add heat-tolerant oil to the braiser pan and set on med-high flame till the oil reaches 375-380F. As soon as the chicken goes in, the temp is going to drop, so have the oil very hot.Then set the chicken in, one by one, with single movements so they lay well in the pan and start to develop a nice brown searing. About 3-5 minutes per side, but you can see the searing and opaqueness coming to the center. Flip when the chicken side is golden brown.Flip, sear, and brown the other side. Remove the chicken and place them on an elevated wire cooling rack. Let them cool for 4-5 minutes.
Use some paper towels to soak up any excessive oil in the pan or pour excess oil out from the pan.
Now add the sauce to that same pan. Let it simmer, very high for few seconds.
Add back the chicken, quickly coating and flipping the chicken in the sauce 2-3 times to get a nice glaze all over the chicken.
Remove from the heat and let it rest for 2 minutes.
Garnish with scallions. Serve and Enjoy!
