Hi Ben,
I beg to differ with Malkore. I've been using agave nectar for two years now in baking, ice cream making and more. It's great stuff. It has the consistency and color of honey without the heavy flavor. It's 1.3 times sweeter than sugar, so while it may be expensive, you use less of it. It reminds me of corn syrup, but not as intensely sweet.
When you bake with it, lower the temperature of the oven by 25 degrees F. Agave makes your food brown a lot quicker than sugar does. Additionally, cut the other liquid in the recipe by a third.
If you want to see how I've been using it, please see my blog,
Altered Plates. I also keep another blog,
Here and There, that has agave recipes as well, but you'll need to use the search function to get a list.
The least expensive place to find agave in bulk is on amazon.com. However, if you're just trying it out for the first time, visit your local health food store and pick up a bottle.
I've been using google.com's alerts on agave nectar for a while, and I've watched the steady trend of increased use of this low-glycemic naturally occurring sweetener. Mostly, it's in the raw foods and vegetarian communities, but there is a growing crowd of "flexitarians" using it as well.
Hope you give it a try. It's really made a difference in my cooking and eating.
Best,
Deb
