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:
2


Ex Input:
I'm dieting, and I use these as a "treat" to myself, when I'm craving chocolate.  I usually brew one of these & one of my coffee K-cups (either plain or hazelnut).  For 60 calories, it's not a bad way to satisfy a chocolate craving when you're on a "calorie-budget!"

Ex Output:

Ex Input:
Twizzlers brand licorice is much better than that other well known brand. If you can get these for $2 to $2.50 a package with free s/h it's a good deal. The black and cherry have good taste; but the strawberry taste was too delicate and barely there
