Question: how many potatoes for 1 cup mashed?
Answer: We found that it took 1 medium white potato to obtain 1 cup of either sliced or shredded potato. When dicing we needed 1.25 potatoes to reach the 1 cup mark. When preparing French fries, it took 1.3 potatoes to result in about 1 cup. However, when measuring for 1 cup of mashed, 2 whole potatoes did the trick.
