Caramel sauce is a sweet topping made by heating sugar (often with butter and cream) until it browns and develops a deep caramel flavor. Traditional caramel sauce is essentially concentrated sugar and is extremely high in carbohydrates, making it incompatible with low-carb, keto, and diabetic-friendly eating.
