The reason some pineapple don't burn your tongue or lips and others do is there is more then one kind of pineapple on the market,the one you want so it won't burn is the super sweet or the golden pineapple, the skin is orangy yellow.They are usually quite large and are in season right now.You might not find them in all the food store but look around they are there, if I can have them in CAnada you can have them anywhere. They are more expensive then the little sour one.
Good luck!
