Arrange chicken pieces with most skin facing upwards. Do not crowd in pan. Use a high heat safe baking or roasting pan. Season generously with salt and pepper.
Roast uncovered at 450° for 15 minutes until skin is browning and crisping.
Meanwhile, prepare glaze by combining remaining ingredients in a small saucepan. Bring to a simmer until slightly reduced and thickened.
Reduce oven temperature to 350°. Brush half of the glaze over top of chicken pieces. Cover and return to the oven for 20 minutes.
Remove foil or lid and brush remaining glaze on top of chicken. Roast uncovered for 10 - 15 more minutes until glaze is caramelizing on top.
Notes
Chicken thighs are an excellent substitute. If thighs are fairly large, add 5 minutes to covered baking time.
Use any variety of mustard and jam, marmalade or pepper jelly for a custom combination.
Adjust amount of Sriracha for heat tolerance.
