Always wanted to make my own hummus and eggplant dip - this brand of tahini I'd never tried before or seen in supermarkets, so I decided to order and try it....excellent by itself or in recipes! Highly recommended.

We got this in the mail and were eager to try it.  I am a huge fan of Izze Sparkling Juice and figured this would be similar to that.  It was in regards to taste, however.....well, let me break it down.  TASTE: I would give it a four!  It had a slight kick to it, that I love.  A little bit of a bitter taste, which my two older boys seemed to like as well.  In fact my 13 year old was bummed when I said we had finished the can.  My husband enjoyed it as well, though I don't see this replacing his daily Dr. Pepper anytime soon.  BENEFIT: It is 100% all natural juice, and it has 100% of your DV of Vitamin C.  Certainly a bit better for you than your traditional soda, but it has just as many calories as a LARGER can of Dr. pepper!  So, i fyou are like me and have maybe one carbonated beverage a day, calorie wise you aren't doing yourself any favors by switching to this.  I will stick with my Izze Blackberry.  3 stars.  VALUE: 1 1/2 stars, MAYBE 2.  You get 24 8 oz cans for 23 dollars.  Hardly a bargain in today's economic climate.  I like to treat myself occasionally, and a sweet treat is certainly one way I often do that, but 23 dollars for 24 cans of this!  Nope, no way, not happening.  Bottom line:  It was tasty, and we enjoyed it, but this isn't something I can see myself buying for my large family.  The benefits just aren't there, not when I can get 100% real fruit juice at the store for 3 dollars a gallon, and add a bit of soda water myself for another buck, if that.  Save your money

This is delicious hot chocolate. It is best at 8 oz cup, but can be stretched to 10. And 8oz of strong coffee and you have delicious mocha
