The Ingredient: Mastic

In Greece one name for mastic is "tears of Chios," a reference to both the island where the resin is produced and the shape of the dried droplets­­, formed when farmers carve incisions in mastic trees that allow the resin to seep out onto the ground and harden. Legend has it that in the 16th century, during the Ottoman reign of Chios, mastic was worth its weight in gold, and by order of the sultan, the penalty for stealing it was execution. It was used as a chewing gum and breath freshener—especially favored by the sultan's harem—as well as a snakebite remedy, filling for dental cavities, food preservative, antibacterial and antifungal agent, and flavoring for certain foods.

Mastic is still a common ingredient in the Middle East, where it's used in desserts including ice cream, cakes, pastries, Turkish delight, spoon sweets (preserves eaten with a spoon), puddings, and bread, as well as liqueurs and nonalcoholic beverages. Pastry chef Jeremy Brutzkus of Longman & Eagle, challenged to make a dish with mastic by Courtney Joseph of Takashi, says the ingredient has a "light juniper, piney flavor . . . slightly tannic, with a little bit of bitterness to it. It's unique."

Because mastic isn't water soluble, Brutzkus said, he had to incorporate fat into the dish somehow. He considered making ice cream or custard, but deemed both "too easy." Instead, he used the mastic in multiple components of a honey-themed dessert: poached kabocha squash, lemon-mastic granita, honey "chicharron," honey pudding, caramelized honey ice cream, honey foam candy, and pine nut powder. "Basically I was trying to figure out how to carry the flavor into the other ingredients. Honey was a seamless flow into the musty, kind of piney flavor of the mastic," he said.

To incorporate the mastic into the dish, Brutzkus first pulverized it and cooked it into a syrup with sugar and water. "If you heat it, it'll turn it into almost like a piece of tar. Translucent tar," Brutzkus said of the mastic. "It won't dissolve into the syrup; it'll basically extract some of the flavor out of it, and then you end up with a chunk of mastic that binds up on its own."

He strained the mastic out of the syrup before combining it with butter, honey, and vanilla paste to make a poaching liquid for the kabocha squash. Once he'd added fat to the liquid, he was able to add the chunk of mastic back in and emulsify the whole thing so that he'd have actual mastic in the dish rather than just the flavor. The granita was mostly mastic syrup, combined with water and a little lemon juice and zest and flavored with vanilla bean and star anise.

Most of the honey elements of the dish incorporated various starches, gums, and powders usually associated with molecular gastronomy. Caramelized-honey ice cream was thickened with xantham gum, honey pudding with agar. A honey "chicharron" was honey, vanilla, water, potato starch and maltodextrin cooked down to a paste, smeared on a Teflon mat, dehydrated in the oven, then deep-fried. Brutzkus called them "little pseudo-pork rinds . . . it has that same texture and bubbled look, but you taste the honey." He also had a variation on honeycomb, a classic confection made with honey and baking soda, that he called honey foam. To finish, he created a pine nut powder to echo the pine flavor of the mastic.

Tasting the dish, Brutzkus said, "It came together nice. [The mastic] adds kind of a bitter undertone, which I like. It adds a nice hit of bitterness to the squash, which is kind of unctuous and well-rounded in terms of texture and weight of flavor. And then the other components are just kind of bright and fresh, outside of the caramelized components. They bring a nice sweet/savory/wintery kind of feel to the dish."

Who's next:

Andrew Brochu of the Aviary, challenged by Brutzkus to make a dish with milk jam. "Essentially it's a form of dulce de leche," Brutzkus said, but instead of starting with condensed milk, you cook down fresh milk and sugar until they caramelize. It "leaves room for interpretation," Brutzkus said—among other possibilities, there's the option of infusing the milk with another ingredient.
