Final answer:
The exact measurement of provolone cheese needed for the White Cheddar Mushrooms is not provided, but an educated guess based on typical recipes could range from 1/4 cup to 1/2 cup.
Step-by-step explanation:
The measurement of provolone cheese to be scattered over the White Cheddar Mushrooms before melting is not directly provided in the question or the provided references. However, using the information given about cheese and conversions, we can attempt to deduce the likely measurement for a similar scenario. The conversion factor mentioned is that 1 cup equals 16 tablespoons. If Henrietta requires 56 tablespoons of Romano cheese for her salads, we divide 56 by 16 to find the number of cups. This calculation results in 3.5 cups, which is equivalent to 3 1/2 cups of Romano cheese. Since grades are not direct conversion measurements, one cannot accurately deduce the specific amount of provolone cheese for the White Cheddar Mushrooms without the recipe's specifics. An educated guess based on standard cheese topping amounts for dishes could be 1/4 cup to 1/2 cup, but this is speculative.
