My First taste of Harisa wasn't in a spice-scented market in North Africa. No, it was at a farm in upstate New York, in the dead of winter. I used a recipe in a book whose title I have long forgotten. Looking like a simple dark pepper paste, it was nothing less than transporting–an accompaniment with the power to eclipse the main course. It changed my culinary life. Really. 
 

I barely noticed winter’s chill that season as I began rubbing harisa’s mahogany magic onto my roast chicken, spooning it over my fish and brightening my roasted vegetables. Spicy, sure, but dark and mysterious in flavor as well as color. Just pre-paring it filled the kitchen with an intoxicating fragrance that compelled me to make it over and over. (Friends demanded jars of the stuff.) I have been in love ever since.

Harisa comes from the Arabic word for “to break into pieces."
Clifford Wright, scholar of history, food and culture and author of one of my favorite books, A Mediterranean Feast, explains that harisa (pr. ha-REE-sa) comes from the Arabic word for “to break into pieces.” For harisa, this is done by pounding hot chilies (ancho are my favorites) in a mortar. “This famous hot chile paste is also found in the cooking of Algeria, Libya and even in western Sicily where cùscusu [couscous] is made. In Tunisia it would be pre-pared fresh in a spice shop,” Wright observes. The simplest recipe, he says, “is merely a paste of red chilies and salt that is covered in olive oil.”



Today harisa is so woven into the cuisines of North Africa that you might assume it has always been there, but if there has ever been a great reason for immigration, free trade and porous borders, this is it. There would be no harisa if one of the New World’s most famous vegetables hadn’t turned up the heat on virtually all of the Old World’s cuisines.

Before chilies came to the Old World, there were varieties of black pepper, Szechuan pepper, cloves, cinnamon, ginger, mustard and horseradish to warm palates from China to London. Ancient China and the Mideast had salty condiments like soy, which was originally a paste, and the equally salty murri in the Fertile Crescent. Black pepper, though both widespread and prized, was rarely a stand-alone condiment—unlike mustard, which has been on the menu in China for at least 2,500 years and appears in medieval recipes from the Middle East, Africa and Andalusia as well as Europe since Roman times.

Soon after capsaicin-bearing New World peppers landed in North Africa, cooks began using local sweet spices like caraway and coriander to transform dried peppers into early variations of the harisa that now, some six centuries later, is enjoying a new global popularity. Walk through New York’s West Village or a few boulevards in Paris, and you find it spooned over falafels or heating up a tagine. From Spain to San Francisco, it’s even showing up in non-traditional recipes like a grapefruit vinaigrette or a salad with wheatberries, carrots, dates and yogurt. I have been known to add it to mayonnaise to take a chicken sandwich to an unprecedented level; blend it with brown butter on Brussels sprouts; even dot it on pizzas. And why not? Its complex heat seems to bless everything it touches, and yet it is easy enough for anyone to make.

Wright suspects harisa—or at least the idea for it—may have come from the New World with the peppers them-selves. “One could argue that the Peruvian aji panca en pasta is such a precursor,” he says, explaining that, like harisa, it is made with rehydrated chilies. “When you think about the way new food ingredients are sold in a market, one of the first questions any prospective customer will ask is, ‘What do you do with it?’ These dried fruits from a magical New World would be an easier sell if there were techniques, recipes or even a sample,” he adds.

My own favorite recipe (above) remains close to the harisa I fell in love with. Instead of reconstituting the dried chilies, I toast them to concentrate their flavor. Then I pulverize them, together with spices and garlic, and I stir in the oil at the end. It keeps at least a year in the fridge—if you can let it last that long. My very favorite way to have it is slathered with honey on a buttery flatbread such as a crepe-like Moroccan m’semme, sprinkled with black olives and sometimes a bit of goat cheese. This addictive combination of hot, sweet and salty is a popular street food in North Africa—edible evidence of why chilies spread through the world like wildfire with every bite.
