In preparation for the class that I'm teaching about Italian Renaissance cookery, I've been making a few dishes from Italian Renaissance cookbooks for our Sunday dinners. This is one of those dishes, although it may or may not count strictly as "Italian." The author, Ruperto de Nola, was the chief cook to Fernando I of Naples, who ruled from 1458 - 1494. This would argue strongly for the recipe being Italian, and that's actually why I chose it. (Most of the Italian books I have are more Northern Italian in origin, but my own ancestors come from Naples. I wanted to showcase a part of Italy that is often overlooked by historians.) However, Fernando's own origins were Catalan, and up until Fernando became king Naples was ruled from Catalonia. Catalans held many of the important positions in the Neapolitan court and classy dishes were said to be made in the Catalan style. While Nola was a village in Italy, the earliest editions of the text that we have are in Castilian, not Italian (or Catalan, for that matter) and some of the words used indicate a Valencian origin.
Whatever. Even if the origins of this dish are Catalan or Valencian, it was certainly enjoyed in Italy in the period under discussion. It was also enjoyed by diners at a recent Sunday dinner. I do tend to make a lot of eggplant when it's in season for Sunday dinners, because it's my friend's favorite vegetable. One of our guests took me aside recently and said, "Every week I find myself eating eggplant here. I've always hated eggplant, but you always make eggplant dishes I like!" That's the nicest compliment. There weren't many leftovers of this dish. It served 20, but would serve a smaller number easily.
What really strikes me about this dish is that "authenticity" is a concern for the author. Naples was (and is) pretty staunchly Catholic, and medieval Catholicism is not noted for its tolerance of other faiths and creeds. Nola does recommend using "good bacon" as the cooking fat, but then corrects himself: "...or with oil that should be sweet, because Moors do not eat bacon..." The medieval taste in Italy and in Spain was certainly to use bacon, but he acknowledges that it is inappropriate in this dish. It seems remarkable in its acceptance to me.
Something else that seems remarkable is the dish's simplicity. The ingredients, in contrast to many medieval "haute cuisine" dishes, are few and easily obtained. I skipped a step where it appears as though the eggplants are par-boiled - I can't think of a reason to do so other than removing the bitterness, and salting and draining the eggplant is a better way of doing so than boiling them. If you can't find verjuice (the juice of unripe grapes), use white wine vinegar. It's not the same by a long shot, but it serves the same purpose.
Moorish Eggplants (serves 20; approx. $0.45/serving)
4 eggplants, peeled and diced
Kosher salt
8 tablespoons olive oil
1 carton chicken broth (about 32 oz) (This might have been a little more than necessary.)
2 cups grated pecorino cheese
1 tablespoon (or more to taste) ground coriander
4 egg yolks
4 tablespoons verjuice
Equipment:
- Colander
- Wide, deep saute pan
- Small bowl
- Place the diced, peeled eggplants in the colander. Salt generously and let drain at least 1 hour. Rinse well with cold water before proceeding.
- Heat the oil in the pan.
- Add the eggplants and reduce heat to medium. "Sweat" the eggplants until browned and softened slightly.
- Add the chicken broth and the cheese. Mix well and let cook, stirring often, until the eggplants are very tender.
- Add the coriander. Mix well.
- Combine the egg yolks and the verjuice in the small bowl. Beat well, then add to the eggplant mixture.
- Stir well and let cook until the sauce is thickened.
- Serve warm. This dish works quite well if prepared in advance and reheated.
