    I had a bunch of leftovers from my pizzas last week, so I cooked up a tasty burger this past Friday with them. I love having leftover ingredients because sometimes I get extra creative about how to use them, and rather than conceptualizing a dish for a week like I normally do, I just get to improvise. That’s where this awesome squash mustard came from

    Some people have been calling me out on the unsightly outlet that is popping up in all my pictures. But did you know that it is code that an outlet needed to be there? Not that I understand building code. But also, its a pretty convenient outlet.

    Roasted squash goes into the food processor until smooth. Next I added the mustard seeds that had been cracked and heated up with some vinegar.

    Beautiful mustard texture. This was bitter with a little sweet from sugar and the squash. It also had some tang from the vinegar. All in all a tasty mustard that I am excited to try on sandwiches this week!

    I fried up the sprouts real quick.

    The burger hit the spot and the mustard went perfectly.

    The squash flavor isn’t exactly the star of the meal, but in the mustard it adds a nice background sweetness and flavor, and it also gives the mustard a nice body.
