Insert the probe into the thickest part of thigh and set the thermometer for 175 degrees. At this point you just need to monitor temps. After 45 minutes remove the bricks and carefully flip the chicken over. The skin should be a nice golden color. Brush the top with melted butter and squeeze a little lemon juice over the top. Close the lid and continue cooking the chicken until the temperature hits 175⁰ in the thigh about 15 more minutes.
