Question: how many cups in 1 sweet potato?
Answer: We found that it took 1.25 medium sweet potatoes to obtain 1 cup of sliced potato. When cubing, we needed 1.3 sweet potatoes to reach the 1 cup mark. However, when measuring for 1 cup of mashed, 2 whole sweet potatoes did the trick. Today sweet potato fries are very popular in more trendy restaurants.
