The small, white popcorn is the best!  Very delicious - and I've tried lots.

THis product (which i am not allowed to return) has ingrediants of salt, spices, hydrolysed soy protein, that last item is the common industry con for adding msg to your food. Every soup on your grocers shelf contains msg, but, i digress. So, the third ingrediant is a form of MSG, further down the ingrediant list is proudly displayed ... Monosodium Gludamate, ...MSG. This does not add spice to your food, it stimulats your tongue into feeling that the food tastes good, when IT DOES NOT. MSG can make dogfood taste like hamburger. anyone who thinks this is making their food taste cajun may be serving ALPO.  Tones and Durkee (sp) do not contain MSG, I prefer Tones!  I have 8 eight ounce cans of this stuff.. would anybody like to buy some hamburger from me?

If you love green tea then you will be impressed with this green tea powder. The instructions say to add one packet to 16 ounces of cold water but I'd recommend you try two packets and one packet (0.35 oz) of stevia. The flavor of the tea with only one packet is fairly mild, so mild in fact that you can barely taste the green tea flavor. When you order this tea you will get six boxes with 12 packets in each. If you use two packets per bottle of water you get 36 drinks. That is only .47 cents per drink if you get free shipping - I ordered some books too. I think that is fairly reasonable. I look forward to trying this tea in shakes and with fruit juices. A website is given for additional recipes. There are a few interesting recipes like the ones for "White Chocolate Green Tea Ice Cream," "Green Tea Papaya Nectar" and "Green Tea Sugar Cookies." You will probably find many uses for this and I've even used the tea powder to make a lovely hot tea. Just use one packet per 8 ounces of hot water. No brewing required. This tea dissolves very easily in hot or ice cold water. I can highly recommend it to you.  ~The Rebecca Review
