Here's a good description of EMDR from Dr. Edward Hume at PShrink.com: When a patient and a therapist do EMDR, the therapist asks the patient to bring to mind the incident the patient wants to work on, the negative thinking caused by the incident, and the new thoughts the patient wants to have.
1 pound is 16 ounces. 8 ounces is 1 cup. so therefore, 1 pound is 2 cups. So for three pounds of ricotta cheese, you would need 6 cups. 3x1 =3 x2=6.
So a recipe that calls for 4 ounces of grated cheese means by weight. If you grate cheese and pour it into a measuring cup to the 4 ounce mark, it will weigh only about 2 ounces. If you can't find a conversion you need on this page, you might try OnlineConversion.com.
