Pasta al Limone

 This week’s recipe is from Sicily, not Rome, and yet you’ll see so many similarities to the process I laid out in our Roman Pastas series. Sicilians are famous all over the Mediterranean for their citrus crops, especially their lemons. Accordingly, pasta al limone has been an instant hit from the moment of its inception.

I mentioned several times throughout the previous series that a keystone of Roman cooking was to source only the best ingredients and to use them well and simply to create something so much better than the sum of their parts. This is also completely applicable to the cuisine of an island a few hundred miles to the south, in Sicily. It is important to remember that by no means is Italian cuisine monolithic, but that nevertheless, the same basic fundamentals apply to food from any region.

This pasta recipe is one of the fastest I’ve ever put up here on the website. It comes together in the amount of time it takes to boil the water and cook the pasta, very similarly to cacio e pepe.

In fact, think of this as a derivative or descendant of cacio e pepe. Recall that for basic cacio e pepe, a pasta is boiled, a paste of pasta water, pepper and pecorino is made, and then the two are combined until emulsified with extra reserved pasta  water. We will follow the same basic steps, and our only modification to this process will come in how we deal with the stars of the show here, the lemons.

Before we get to the specifics on this simple recipe anyone can make—even on the tightest of budgets—let’s talk citrus. As a note to any Brazilian or otherwise Lusophone readers: My family originally comes from Brazil, and so I know that in Portuguese, there aren’t distinct words for “lime” and “lemon” as there are in English. In Portuguese, we differentiate yellow from green by the location which we add to the generic word that means both “lime and lemon.” If a fruit is a “Sicilian lemon,” then it’s a “lemon” in English; if it’s a “Tahiti lemon,” then it’s a “lime.” For any readers from the Lusophone world, this recipe is meant to be made with the former, not the latter. And for those of us in the US or elsewhere where a distinction exists between generic “lemons” and “Meyer lemons,” this recipe is meant to be made with the former; Meyer lemons are sweeter than regular lemons, possibly as a result of crossing regular lemons with oranges or clementines to create the Meyers. That extra sweetness in the Meyers won’t work with this dish, so make sure to get the best regular lemons you can find.

The lemon will be the star of this recipe, so don’t be shy with it. Wash, zest, and juice 2 whole large lemons. Be careful to only scrape off the outermost yellow part. That yellow outer layer is almost entirely natural yellow pigments and scented oils which together make lemons very aromatic, all of which we want to make use of in our final dish. That layer, however, is very thin, and directly underneath it is the much thicker and far more acidic layer of white pith. Generally, don’t get any—or get as little as possible—of the pith when zesting citrus of any kind (oranges, limes, lemons, grapefruits, etc.). Either before zesting or between zesting and juicing, roll your washed lemons against your countertop or another flat surface. Doing so weakens or even pre-ruptures some cell walls inside the lemon, thereby making juicing easier later, and increasing yield at that point.

We will also make use of fresh mint to balance out the acidity in this dish. Fresh herbs like mint and basil bruise very easily when hacked at indiscriminately with a knife.

Place 2 tablespoons of extra virgin olive oil in a wide, shallow pan, and as the oil warms, place the zest into the oil together with a few leaves of mint taken directly from the plant, without any chopping or tearing. There are several compounds in both mint and lemon zest which are (only, or in some cases, more) soluble in oil versus water. When the oil becomes noticeably aromatic, turn off the heat and remove the mint leaves.  

Cook 1 pound of a long, dry pasta according to the manufacturer's instructions to al dente doneness. When 3 minutes remain, reserve 1 ½ cups of pasta water. Grate 1 cup of pecorino Romano or Parmigiano Reggiano and combine it with the juice and zest of the two lemons juiced and zested earlier. Take 2 tablespoons of that pasta cooking water and combine it with the cheese and lemon juice and zest so that a thick paste forms. Season this paste liberally with black pepper, just as one would make cacio e pepe.  

From here, the process is identical to cacio e pepe. Drain the pasta once it is al dente, and combine it with the aromatic oil, the cheese-zest paste, and thin and emulsify the sauce by gradually adding pasta cooking water and tossing. Garnish with black pepper, Parmigiano Reggiano, lemon zest, and fresh mint leaves.
