Haven't tried the Steel's stuff. Walden Farms has a good 0carb chocolate syrup, though.

One pouch of the notStarch lasted me nearly a year!! You only use a wee little bit (as I learned in the inaugural gravy attempt.....<shudder>) It works in hot or cold things.

Some people use xanthan gum (a component of the notStarch) for thickening salad dressings. Maybe you can find a thread unter the recipe forum "tips and techniques" section?
