Great sauces can save a badly cooked piece of chicken. However, a bad sauce will ruin the best cooked meal. Being able to consistently create flavorful and smooth sauces is one of the best skills to have in the home kitchen.
When you can make a variety of sauces, you multiply the number of meals you can create. A grilled chicken breast is an entirely different dish with a white cheese sauce over it than a dark Cajun spicy sauce. It’s still a chicken breast, but now it’s two different meals.
