Come on Amazon, give me a break.  Powdered tofu?  Get in some real food and I'll buy more from you. I went looking for table sugar. You've got 100 weird kinds of sugar (that you expect me to buy in bulk!) but NO just plain sugar. I'm not eatin' any more of this rice and tofu bread either.  Sorry I just had to rant.

Ex Output:

Ex Input:
My kids loves Chips Ahoy! and I will have them once in a while as well.  But the kids refuse to eat them from this Family Size package.  Once I tasted them, I knew why.  They have an awful medicinal taste.  Really bad.  I don't what the problem is, but if you like Chips Ahoy, you will not like these.  Go elsewhere.

I bought this becaue they were $9.99 for the 24 pack.  I could try them for .50/cup.  Other in the store were almost $1/cup.  Overall they are ok/good but you need to run a hot water flush throuhg you maschine afetr each use or there is a potential to have the residue gunk up you drain area.
