Heat a 17cm or 7" saucepan over a high heat, and when it's hot, add the beer, the honey, treacle and Worcestershire sauce and reduce by two-thirds.
Whisk in the mustard, paprika, chilli powder and pepper and set aside to cool.
Peel back the skin of the chicken drumsticks and season with lots of salt, then roll the skin back up, then dip them into the glaze and rotate to coat.
Oil up your grill grate and then drop the chicken drumsticks over a direct heat. Keep basting the chicken and keep them moving to get a nice colour on each drumstick.
Move to the indirect heat and close the lid, then cook for 30-35 minutes or until the internal temperature reaches 70°C or 158°F.
Rest for 5-10 minutes and check that the internal temperature has reached 73°C or 165°F before serving.
Oven Instructions:
Follow steps 1-5 above.
Place the drumsticks onto an oven rack that allows air to circulate underneath.
Heat a fan-assisted oven to 220°C or 450°F and place the drumsticks in and cook for 20 minutes.
Reduce the heat to 180°C or 350°F and switch off fan assist mode.
Cook for another 10-15 minutes or until the internal temperature reaches 70°C or 158°F.
Rest for 5-10 minutes and check that the internal temperature has reached 73°C or 165°F before serving.
