Like many academics, Ligia Ravé turned to writing fiction after a career as a professor (teaching architecture at Penn and Tulane). Unlike many, however, she developed a new expertise along the way: Sephardic Jewish food.

Ravé developed her culinary expertise while researching her debut novel, Hanah's Paradise, a family saga recently published by Philadelphia's New Door Books.

The book centers on the Ravayah family and its mystical Galilean homestead, known as Hanah's Paradise. This far-flung Jewish clan has an ironclad family tradition: Before marriage, each firstborn child must travel to Hanah's Paradise at Passover time and record the family's story in the archives.

These chronicles, kept since medieval times, hold volumes of writings, drawings, music, and recipes from every corner of the world. Part detective, part coming-of-age story, the novel follows Salomeia, a young woman exiled from Communist Romania, who arrives at Hanah's Paradise to become the new keeper of the family archives.

Salomeia discovers long-hidden stories of her relatives through 500 years of Jewish Diaspora: living, loving, and being exiled from countries all over Europe and the Middle East. Sifting through the archival recipes, Salomeia also discovered that a family carries on its culture to future generations through its food.

The author researched 400 years of Sephardic culinary history for the book, and includes recipes that are both historically accurate and irreverent: one for baccalao dao reina reads in part, "Keep a slab of dry cod in water for one day and one night. Keep the pot covered and change the water many times. At nighttime, Angels use uncovered pots to relieve themselves."

Ravé recently prepared a Passover feast from some of these recipes in her kitchen in the expansive modernist home at 12th and Latimer Streets that she designed with her husband, architect David Slovic.

The house is built around a half-octagon courtyard filled with towering golden bamboo. The savvy reader will note the same bamboo in the book, growing lavishly in the octagonal courtyard at Hanah's Paradise.

The 15th century was not an impressive time in Jewish culinary history, Ravé said as she cooked in her compact kitchen flooded with morning sun from the floor-to-ceiling glass wall. People ate wild leeks, wild asparagus, oranges, and that was about it for flavor.

"There wasn't much diversity then," she said. "They ate a lot of roots." To put together a colorful and flavorful Sephardic-inspired Passover meal, it's best to look to a time after the spice trade became well established. Jewish merchants were instrumental in establishing trade in important spices like pepper, nutmeg, and cloves throughout Europe and the Middle East.

In her novel, the physical space occupied by Hanah's Paradise begins as a trading post, a place where the roads to Africa, India, and Spain converge. Caravans came to such outposts to trade spices, silk, rugs, sacks of grain, amber, and salt.

Ravé selected four unleavened, delicately spiced recipes from the book. She began with Torta alla Giudia, a classic dish modified for Passover. Also known as Pizza Hebraica, Torta alla Giudia is a kind of not-very-eggy quiche traditionally prepared with spinach and green vegetables layered over a bread crust.

The dish works well for Passover, Ravé explained, because its vivid green color represents renewal. It is modified with a crust made of matzoh dipped in chicken broth. Ravé prefers to mix in flavored matzoh meal with the spinach, edamame, and artichokes. Prepped for the oven, the dish looked a bit like a lush spring garden.

The next dish, saffron-rich Red Fish Soup, came from a branch of Ravé's fictional family that lived in Portugal but was forced to convert to Catholicism during the Spanish Inquisition. "Food was a way of maintaining identity in the face of persecution," said Ravé. "Trying to survive in a world where you're not allowed to be who you are."

Ravé's characters were remarkably inventive in finding ways to appear Christian but remain Jewish. Converts were forced to quit keeping kosher or Sabbath, so they hid the religious food rituals.

One character took to her bed every Friday with a mysterious ailment that required a glass of red wine and a piece of bread. She celebrated the Sabbath in her room, away from spying neighbors and servants who might rat her out to the authorities.

Another character went out of her way to serve pork, shellfish and other non-kosher dishes to visitors; however, she filled the plates with salad greens, hiding the food underneath, so that the visitors couldn't see that her own plate was bare of "forbidden" trayfe.

Lemon chicken was Ravé's main dish, inspired by a scene in the book in which more than 100 cousins from all over the world gather for Sabbath dinner at Hanah's Paradise - each family cooking a dish from its home country.

While the logistics are hard to imagine, the scene is a lovely culinary fantasy of far-flung relatives and their cuisines united through a Friday night chicken dinner: "When chicken was on the menu, the Moroccans made Daphna de poulet, a chicken stew with pickled lemons and green olives; the Spanish family cooked chicken with almonds, lemons, and apricots; the Egyptians cooked it with walnuts and mint leaves. The Russian cousins roasted it with onion, garlic, and peppers. The Polish stuffed it with mushrooms. The cousin from Budapest made a goulash with sweet paprika. The Greek answer was chicken with olives and marjoram. The Indian cousins used curry and tomato chutney. The Iranians used pomegranate syrup, the French produced Poulet Basquais, the Americans barbequed the breast, and the Germans made schnitzel. I made my own."

The dish Ravé (and her narrator) selected was a remarkably flavorful and practically fat-free chicken salad, with an exquisite mix of textures and flavor from preserved lemons, red peppers, capers, and slivered almonds.

The secret to a good lemon chicken: "Boil the chicken to death," Ravé said. Then refrigerate, separate the meat from the bones, mix with spices and capers and preserved lemons, and refrigerate again. The dish should be served at room temperature, meaning very little time has to be spent on last-minute prep in the kitchen.

Garnished with almonds, the chicken looked tantalizing served next to the green torta. Ravé finished the menu with an easy dish of stuffed apricots. She boiled an orange rind to remove its bitterness, and added it to a bit of almond paste and a dash of rosewater.

A quick spin in the food processor, and the mixture was ready to be stuffed inside peeled apricot halves. The stuffed apricots looked like eggs: another symbol of renewal and rebirth. Each tasted like springtime.
