Sometimes you just get a taste in your head. Like a bad song from high school, no matter what you do, you know there’s only one way to get it out, which is how you came to find yourself in Best Buy at nine o’clock at night trying to decide between “Becoming X” and “Best of the Sneaker Pimps.”
Well, a couple of months ago, a very specific flavor rolled into my head: the sicilian sweet and sour flavor. An amalgamation of wine, tomatoes, sugar, vinegar and sometimes honey, it’s a singular taste that can’t really be explained. It’s richer than what Americans think of as Chinese sweet and sour, much subtler and infinitely more complex. Imagine a tomato sauce a little on the sweet side with an astringent background note that doesn’t quite make you pucker, but stays with you nonetheless. The subtlety comes from long cooking, and often one or more of the sweet and sour components disappear completely, like in *polpo agrodolce*, sweet and sour octopus, which has tomatoes in it, but you’d never know.
Sometimes the sauce is left slightly out of balance, and ingredients are added at the end to shift it one way or the other, like currants or raisins for sweet, or fresh vinegar or capers for sour. You could cook just about anything agrodolce, probably, and get away with it; though squashes (summer and winter), sprouting vegetables and shellfish seem to have an especial affinity for the treatment.
Last night, I finally scratched the itch with an old-school *pasta al cavolofiore*: pasta with cauliflower. It’s a typical agrodolce dish, garnished with toasted breadcrumbs rather than cheese, which would be at odds with the complex and poignant flavor of the sauce. I took some poetic license this time and used panko breadcrumbs, mainly because I didn’t have any dry bread lying around, and the panko seem to keep their flavor better in packaging than regular breadcrumbs and their larger size mimics fresh.
It’s a big recipe; it will sauce at least two or three pounds of pasta, but it is **fantastic** spooned over polenta and would be equally at home stirred into or poured onto rice or plain risotto. You can pretty much substitute winter squash, broccoli or brussels sprouts directly into this recipe. For zucchini or yellow squash skip the initial blanching, and for eggplant a quick saute in peanut oil should replace the blanching altogether.
I’ve only made this with white cauliflower, but I’d imagine that other colors or [romanesco]( http://en.wikipedia.org/wiki/Romanesco_broccoli) would be equally good, though for romanesco I would only blanch it very briefly.
The pictures of this didn’t come out terribly well, but I included one anyway so you could see the texture of the finished sauce. Don’t let the look of that pic fool you: this sauce is boss.
**Pasta al Cavolofiore Agrodolce**
Pasta with Sweet and Sour Cauliflower
1 head very fresh cauliflower, about 1-1/2 pounds
3 tablespoons extra virgin olive oil
2 medium onions, thinly sliced
5 or 6 cloves of garlic, peeled
2 28 oz cans of whole peeled plum tomatoes, san marzano or bel roma if available
1 to 2 teaspoons sugar, to tase and depending on the tomatoes
2 tablespoons red or white wine vinegar, plus more to taste
1 tablespoon kosher salt, plus more to taste
1/2 teaspoon black pepper, plus more to taste
1/2 teaspoon crushed red pepper flakes, or to taste
1 teaspoon dried oregano, with the blossoms if using branch oregano
2/3 cup dried black currants or golden raisins (or plain raisins)
1/2 cup pine nuts
2 cups homemade (or packaged Panko) breadcrumbs
salt and pepper to taste
1/2 cup or so extra virgin olive oil
2 teaspoons minced fresh rosemary or other herb
Set a large pot of salted water to boil. If cooking pasta, do NOT use the same water to cook the pasta and the cauliflower. The pasta will end up tasting like funky old cabbage.
Heat the oil in a deep pot (at least 4 quarts) and add the onion. Cook over medium heat until softened, about 5 minutes. Season with salt and pepper and add the garlic. When the garlic just begins to turn golden (NOT brown) add the tomatoes and all their juice. Rinse out the cans with some water, but don’t add more than 3/4 of a cup or so to the sauce. Add the sugar, vinegar, salt, pepper, red pepper flakes and oregano. Bring to a gentle boil and cook for ten minutes, stirring occasionally.
After ten minutes, lower the heat to medium and start breaking up the tomatoes with a spoon. Don’t worry about the texture at this point, just pop each tomato so they’re not keeping their seeds and juice separate from the rest of the sauce. Cover partially and cook for thirty minutes or so, somewhere between a lively simmer and a gentle boil. Stir it regularly, as the tomatoes will want to stick to the bottom. If you’re not using a very heavy pan for this, you might want to use a flame tamer (or my ghetto flame tamer, the lid from the tomato can). If it seems that the sauce is too liquid, remove the cover.
Meanwhile, break off the leaves from the cauliflower stalk and cut around it to separate the florets. Trim them into inch or so pieces, then pare away the outer layers of the stalk and slice what’s left (do not throw this part away on any vegetable, including heads of lettuce). Blanch the cauliflower for about 5 minutes, until it is barely softened, but still retains some crunch in the middle. Drain the cauliflower in a colander. Don’t use this water for anything else; it tastes kind of funky.
Put the breadcrumbs into a skillet and season them with salt and pepper. Pour in some of the olive oil, just enough to moisten them. Don’t put so much that there is oil pooling in the bottom. Put this over medium low heat and stir it often, so that the breadcrumbs turn a toasty mahogany color, but don’t let them burn. If they burn, start over: there’s no saving them. When you think they’re getting close, add the rosemary so it perfumes the crumbs. Transfer to a plate when they’re ready.
Cover the raisins with boiling water. Toast the pine nuts in a small, heavy skillet over medium heat, tossing regularly, then transfer to a plate to cool.
After thirty minutes, the sauce should taste more or less like a marinara sauce: bright and fresh, but a little bit sour and a little bit oniony-sweet. The tomatoes should be pretty coarse by this point, but break them up with a spoon to a chunky but regular consistency. Add the cauliflower and lower the heat so the sauce simmers gently. Cook the sauce and cauliflower together for about ten minutes, stirring occaisionally.
Drain the raisins.
After ten minutes, add the raisins and pine nuts to the sauce, adjust the seasoning with salt and pepper and maybe some fresh vinegar if it’s needed or desired. Cook the sauce for five minutes more.
Serve over pasta or polenta, sprinkled with the toasted breadcrumbs.
