When vinegar is first added to warm rice, it gets more slippery 
and then it sticks up when it cools.  Is it the proteins being 
denatured in rice with a H+ catalyst from vinegar?  Why is it 
necessary to add sugar and why does the short rice coated with 
glucose provide stickier results than with brown or long grain?
