Flash Point Determination. The flash point of a liquid is the lowest temperature at which sufficient vapor is evolved to form a flammable mixture in air at standard atmospheric pressure. The flash point provides a simple, convenient index for assessing the flammability of a wide variety of materials. Chilworth generally measures flash points in accordance with American Society for Testing and Materials (ASTM) Method D93-94 using the Pensky-Martens Closed Cup apparatus.
Roast the turkey breast for 1 3/4 hours to 2 hours, depending on your oven and the size of a roast. A meat thermometer inserted into the middle of the breast should read 170 degrees F. when done.
1 Once the oil is heated, slowly lower the turkey into the fryer. The turkey may not be totally immersed in the oil. This may cause the top part of the breast to remain white even though it is cooked to the proper end temperature.  Set the timer and cook the turkey about 3 to 4 minutes per pound.
