A quick Googling of “cauliflower and pasta” later and I was at work, boiling water, breaking down said head of cauliflower and thinking of what to open to accompany the meal. Here’s the recipe, as adapted from Chez Panisse Vegetables via SmittenKitchen (thanks to SK, too, for the cauliphoto).
Gemelli with Cauliflower, Walnuts and Feta

2 heads cauliflower (I used one large head, which seemed like plenty)
1 medium onion
4 small cloves garlic
1 pound pasta (SK used whole wheat penne, I went with regular gemelli)
Extra-virgin olive oil
Salt and pepper
1 pinch red pepper flakes
White wine vinegar (skipped it)
1/2 lemon
1/2 cup toasted walnuts
4 ounces ricotta salata or feta cheese (fresh goat cheese would also do quite nicely)
Serves two hungry cyclists, four out of shape wine bloggers or six “normal people.”
Boil water for pasta. Lightly toast the walnut pieces. Break the cauliflower down into smallish florets then sauté in olive oil until slightly tender. Add very thinly sliced onion and red pepper flakes and continue to sauté while cooking the pasta. When done, the cauliflower should taste “cooked” but still have some crunch. Add minced garlic, remove from heat and squeeze on a little lemon juice (I skipped the vinegar, figuring the lemon and cheese would provide enough acid; plus, I’m really not a big vinegar fan). Toss together pasta, walnuts and cauliflower, drizzle with olive oil, test for seasoning and then top with crumbled cheese. I went with feta – it was what I had on hand – but fresh goat cheese would have been a great choice with the wine I selected.
What was that wine? If I’d chosen the recipe first, then the wine (as I kind of suggested above), I might have gone with a Soave like one of those I wrote up a few weeks back, or with something tasty from Campania, perhaps a good Falanghina or Fiano di Avellino, maybe even something Assyrtiko-based from Greece. But no, my head may have told me those things but my heart was already hankering for Muscadet. And when Muscadet calls, McDuff likes to answer.

Muscadet Sèvre et Maine Sur Lie “Sélection Vieilles Vignes 1er Cru du Château,” Château de la Ragotière (Les Frères Couillaud) 2007
$14. 12% alcohol. Cork. Importer: Vineyard Brands, Birmingham, AL.
This turned out to be quite an easy drinking Muscadet, bursting with lime juice driven flavors. Its soft, medium-acidity, forward fruit and delicate whisper of minerality make it a forgiving choice at the table, less strict than a steelier Muscadet. Indeed, I quite enjoyed it, popped and poured, with our pasta and cauliflower dish. Those same open-knit structural components, though, suggest that this is a Muscadet that needs to be drunk young, a notion supported by the wine’s relative collapse on day two, when its fruit faded, leaving behind a skeleton without enough balance to stand up to food or stand on its own.

More food for thought:
What’s with Muscadet producers and their multiple designations? Granted, this isn’t quite as over-the-top/confusing as some of Luneau-Papin’s cuvée names. But wouldn’t “Vieilles Vignes” have sufficed? I suppose I could just choose to call it "VV" but I’m a bit of a stickler for referring to wines by their full names. (I won’t even go into the bottle numbering….)
