I used a combo of broccoli and cauliflower because it's what I had on hand. Really glad I did! Classic flavor combo and so easy to throw together on roasted vegetables makes this infinitely adaptable. Subbed some garlic oil for the butter, and I was tempted to do as directed and make it all on the sheet pan - but for the sake of cleanup - I roasted on aluminum foil and tossed the florets in a bowl where I'd already whisked the oil, vinegar, and mustard. Perfect!
This did not turn out well as written. The butter and vinegar go their separate ways on the hot baking sheet and are impossible to emulsify. The second time around I pre-melted the butter and whisked it together with the mustard and vinegar in a large storage bowl that has a lid. Then I added the roasted broccoli, put on the lid, and shook it gently for half a minute or so. Worked much better. I also preheated my sheet pan for a nice under-char on the broccoli. Tastes great.
I've made this a few times and find it comes out best if I pre-heat the cooking sheet in a 425° oven before adding the broccoli.
I was underwhelmed. Will try it again without butter (which added complication with no taste payoff imho. Tried someone's advice to double the mustard and vinegar...doubling the mustard was fine but I think 1x on the sherry vinegar is enough.
My oven bakes a cake perfectly well, but 450 was much too high to roast the broccoli. In fifteen minutes, it was already turning black. Otherwise, the taste was good.
Delicious as is. I added just a drizzle of honey… but that is only because I am a sugar addict ;-)
