I have a question about step 4 on the recipe "Aunt Babe's Mashed Potatoes" from F for Food. It says:
"In a mixing bowl add potato insides, 1 and ½ sticks of butter, salt & pepper. With a hand mixer, slowly add diluted milk while keeping an eye on maintaining the moisture. Aunt Babe said that the secret is the moisture.
What is the ratio on the 1/2 diluted evaporated milk? Diluted with water? "
