Just tried Agave this weekend while in Central Market. Vaguely halfway between a maple syrup and a corn syrup taste!
As a diabetic, I really hate marketing like that. It really pisses me off! People could get into trouble! The products may not contain sugar or high fructose corn syrup - but they do contain molasses, tomato paste, agave nectar, beer, Worcestershire sauce, and other "hidden" carbs - all contain sugars of one kind or another or carbs for other reasons. This guys site says a 2 tsp serving has 8 carbs. Two tsp of sugar also contain 8 carbs (depending on which table you look in). - Compare that to Hunts BBQ sauce original - 13g carbs, Smuckers strawberry preserves - 8g carbs, Vanilla Ice cream - 4g carbs. It might me more "healthy" since no simple sugars and high fructose corn syrup - but hardly "low carb". His site never states that they are low carb!
Might be good tasting sauces though - just misleading information!
