You know.....I think some varieties of vodkas come from potatos....maybe there should be a recipe swap......
Oh - geeze Louise ... youse guys made me go dig in the garage to find my analog scales and run some tests ....
A medium sized Idaho/Irish potato (5" L x 2.5" W) weighs about 8-oz (1/2 lb). It would take 3 to make 1.5 lb. Using the water displacement method - about 1-cup per 8-oz (or 3-cups for 1.5 lbs) - but you have to measure by the water displacement method - just tossing raw potato chunks into a measuing cup will not be accurate.
So, Maureen, there is no simple answer for this - it depends on the size of the cubes and how you measure them. It's like asking the question, "How much does a cup of flour weigh?" The answer is, it depends on how you measure it.
If this is for a baking recipe - then the weight might be important ... if it is for a cookery application (potato salad, a soup, etc.) then you have a lot more leeway.
What are you trying to cook?
When a recipe calls for l.5# cubed potatoes, how many cups are needed?
