We have been to Mexico a few times and HATE the "butter" they serve with potaoes and seafood. So we have found a solution, friends of ours went last year and bought real butter from Sam's Club, individually wrapped in little "tubs". It's whipped butter like you would get in individual packets here when you go out to eat. Just keep it frozen before you go and put it in your suitcase between layers of clothes. It is still frozen when you land. And resturant workers love it.
