Because this sauce is so sticky, it may stick to your fingers more than the sauce. But after being marinated in it and then baked in it, the glaze is just a bonus. You still want it to stick, though. Try adding a little more molasses or add a teaspoon of cornstarch. Then, stir it up and see how well it sticks. If it still does not stick well, use it for a dip. It could have been just that it was not cooked long enough. Next time, cook it for an extra five minutes and see if that helps.
