Remove any gizzards from the chicken and place in a roasting pan.
1 whole chicken
Halve the citrus and squeeze the juice over the chicken. Place a few wedges in the cavity of the chicken and arrange the rest around the roasting pan.
2 limes and an orange
Mix the baking powder, onion powder, garlic powder and cumin, and sprinkle the chicken with the mixture and some salt.
½ teaspoon baking powder, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon cumin
Roast the chicken uncovered for about 1 hour and 15 minutes. The formula is usually 20 minutes per pound plus 10 or so minutes. Then let it rest for at least 5. I always test with a thermometer until it's just over 160 degrees. The resting period will get it the rest of the way.
I baked a few potatoes alongside and then popped in some frozen broccoli when I pulled out the chicken to rest.
As you can see I simply cut the chicken in pieces and served.
