I gave up cooking with aluminum decades ago after I got a new aluminum pressure cooker when I was living off grid on sailboats. I was cooking with part seawater instead of salt to conserve fresh water, and washing the dishes with sea water. It only took a month or 2 before the thick aluminum pot was full of pinholes, I guess from exposure to seawater! Later I read somewhere that aluminum exposure is linked to Alzheimer's. Also tiny bits of aluminum scraped off a pot react with the fillings in my teeth and give an awful metallic electric taste. I'm all stainless steel, glass, and enamelware now. You ever notice how the aluminum foil on the lasagna is full of holes when you take it out of the oven? I guess the acid in the tomatoes dissolves aluminum and deposits it in the lasagna...
