Paula L. says
Wow this is flavorful! I honestly don't hold out very high expectations for cauliflower unless its maybe deep fried or smothered in curry but took a chance on this recipe. That paid off big time! I'm thinking, dijon mustard? The sauce was simply scrumptious and was perfect for the whole roasted cauliflower which I carefully basted both before and after roasting. I didn't have any white wine so I used marsala wine instead which was no doubt different but did seem to work very well.

Hi Paula! Thank you so much for taking the time to leave this! I’m really happy you took a chance on the cauliflower and that it surprised you in the best way. The Dijon really does a lot of the heavy lifting in that sauce, right? Marsala wine was such a clever swap, too. I love when a recipe is flexible like that and still turns out delicious. Thanks again for sharing your tweaks and for trying the recipe — you made my day!
