I am on a low glycemic index diet to help control my blood sugar and hormone levels. My nutritionist recommended agave nectar as a sweetener since it's GI index is in the low 30's as opposed to honey in the low 50's and sugar in the mid-50's. I've tried supermarkets, health food stores and wholesale clubs. The prices are usually around $13 for a 32oz bottle and this is $19ish for 2x46oz. It's used like honey - substitute 2/3c for every 1c sugar and reduce liquids by 1/4th.  I also use it in a carrot cake recipe (equal substitution) instead of sugar where I substitute whole wheat flour instead of white flour and I don't decrease the other liquids. It's delicious and you'd never know that's it's actually good for you.

This tea has NO flavor, tastes like dust It "looks" like quality -- pretty package -- but it's no good. Lipton regular Pekoe is farrr superior.

Not sure it should be legal. We put this --and a few other spices I won't share here--on some lamb chops and just fried them. They were AMAZING. This spice tastes pretty hot by itself, which makes it a bit hard to figure out how a blend with it and other spices is going to turn out. The end result, strangely, was not hot at all. Since I like spicy, I would usually have been disappointed, but this was so good, I did not even CARE. Seriously--you have to try this. I ordered two other spices at the same time, neither of which will be getting a GOOD review.
