When cooking chicken on a BBQ there is always the risk that it is never cooked through correctly. The amount of times I have been to a BBQ and been served chicken that has not been done correctly (still pink inside) has happened to many times to mention. In some cases people don't even BBQ chicken because of the risk.
So here are my tips on getting your chicken right.
I prefer to BBQ chicken breasts, a good way of BBQing chicken breasts is actually to place them between cling film sheets and flatten them with a mallet. The benefit of this is now that they are flat they will cook a lot faster and are easier to turn.
Always have a knife and fork present so you can cut into the chicken. If you are cooking chicken legs ensure you cut through to the bone to make sure the chicken is done. Never rely on how the chicken looks on the outside. Remember just because its burnt on the outside does not means it done. If the chicken is burning raise the grill a level up and allow the chicken to cook slower.
Remember its better to cook the chicken slower so it doesn't get burnt but is cooked thoroughly.
Get yourself a BBQ thermometer, these usually come in the form of a BBQ fork you can use to test if the chicken is done.
Happy BBQing!
