When Tommy doesn't like a kind of food he gags

I was trying bananas for the first time and he started gagging.  I thought hmm, that's weird and I looked at the ingredients.  It was bananas and lemon juice.  I thought hmm why lemon juice.  I figured ok I'll try bananas without the lemon juice added and sure enough he loved them.  No more baby food for us with added lemon juice.
