I have a history degree. Even though I never use it, I am always interested in old thing culture, people, artifacts… So when Maille asked us to sample their mustard and create a recipe, the 1747 on the label peaked my interest. Its easy to learn about Maille’s history. They are proud of it and rightly so! The founder of the company, Antoine-Claude Maille, became the official supplier to the court of Louis XV in Paris in the same year he established this company, and later, Maille Mustard graced the table of French and English Kings and Queens throughout history.


Maille sent us 5 different mustard’s to try. White Wine mustard, Dijon Blackcurrant mustard (yup, you read that right), Lemon and Harrissa, Walnut flavored mustard, and Parmesan Cheese and Basil mustard. Right away, Debbie and I gravitated to the White Wine mustard and the Parmesan Cheese and Basil mustard. Of course we tried the others. We think the Lemon and Harrissa mustard would add an interesting and tasty twist in our Caeser salad.

Maille Mustard is very different from the yellow mustard that most of us are accustomed to. It is rich and strong with intense flavor.



We decided to use our favorites of the Maille Mustard to make some stuffed portobellos. We used the mustard two ways in this dish. First we mixed the Parmesan and Basil mustard with a little bit of butter and painted the insides of the mushrooms. The mixture slides down in between the gills of the portobellos and fills them up with beautiful buttery mustard flavor.

We also made a white wine mustard cream sauce that we drizzled on top of the shredded chicken filling that is mixed with zucchini, sundried tomatoes, and bacon. That sauce is to die for! Creamy and savory with a distinct character of white wine and slight mustard bite.

The sauce is also amazing with pan fried scallops on a bed of pasta.

This meal is perfect for the warmer weather were having these days. It’s light and perfect for an evening on the patio. Or lunch for that matter. I love a dish that doesn’t sit heavy but still feels slightly decadent and totally satisfying.

If you were feeling a little cheesy, you could sprinkle some cheese on these when you bake them. Gruyere would be nice. Or Parmesan or Asiago.
