What would you chose between practical and good-looking ? I just bought an aluminium dish to keep the milk in it , and it keeps for about 5 days until the smell starts to change , and she wants a teflon pan that keeps the milk without changing smell only for 2 days! what should i do ?Why are you putting it in a pan? Aluminum is probably better as Teflon is not necessarily as safe as thoughtAluminum is pretty non reactive, hence not smelling as quickIf this is for a cat, I wouoldn\'t leave it out of the frig for more than a day or two anyway.Other related question
