My first year I boiled on a 2x3 SS pan and a friend boiled on English tin and finished it in an aluminum pot on a turkey fryer. My wife and I each sampled his and he ours. After we got back in our vehicle, we both agreed his had an aluminum after taste. Cooking in aluminum has sometimes been thought to be one possible cause of Alzheimer's. I decided I would not take the chance, my memory has nothing to spare.
