advice please

Sorry for the delayed reply, Jen. The most common method seems to be to reduce the amount of cream that goes into the caramel sauce. Alternatively, you can add a little cornstarch to the sauce. I'd mix maybe a tsp of cornstarch with a tsp of cream and blend it into the caramel. You can continue to add more cornstarch to get to the desired thickness. A little goes a long way though, so start small and add as needed!
