    oh wow, this cheese sauce looks delicious. I never thought of adding dijon mustard to a cheese sauce and this has me salivating. Going to give it a try this weekend. Thanks for the recipe.

    OMG, this cheese sauce is so good I could drink it. The flavors were balanced, the texture was perfectly creamy, and it was so simple to prepare. I served it over steamed broccoli and cauliflower and the whole family loved it.

    Made this sauce for my cauliflower cheese dish which we will be having with our roast lamb tomorrow night. I was licking the bowl after I made it; so delish and perfect for a much better and healthier version of traditional cheese sauce using flour and milk. Nom Nom!
