Once shoppers spot them, they tend to react the same way: First, they admire. They ask questions. Then they buy the gelatinas in dinner-party-size lots until they are gone. Customers who arrive at the co-op in late morning never see them.
The fruit-flavored desserts, popular for decades in some parts of Mexico, are dramatic and novel, at the price point of a designer cupcake but with lots of protein, no fat and few calories.
"They can't believe the way we make them," Gamboa says.
The process makes the outcome seem all the more remarkable. Trained hands can create a blossom in less than 10 minutes. (Check out the "gelatina artistica" video on YouTube.) Working in a palm-size hemisphere of freshly set gelatin, Gamboa uses hypodermic needles - some straight, some bent into a U - to inject colored mixtures of gelatin and sweetened condensed milk. It is done while the gelatin is inverted, so it's a little like sculpting a figure from the feet up. Each stab or swath is instantly encapsulated, forming a leaf or petal or stamen. Slight corrections can be made if you're skillful enough; otherwise, it's art without a do-over option.
In Mexico, gelatin desserts are at home on just about every buffet table for quinceaneras and other family celebrations. They're festive and inexpensive, often molded into cake-pan shapes and not as wiggly or translucent as Jell-O. Gamboa, 41, grew up in Mexico City but saw gelatinas for the first time only last year, sold in a pastry shop there.
Canela Bakery is known for its fine selection of sweet and organic breads. Gamboa and her business partner, baker Eloy Resendiz, have owned the business for three years; she looks almost sheepish when she admits she was trained as a nurse, is good at organizing and doesn't bake much herself.
But she was so taken with the thought of gelatinas that she wanted to offer them at Canela. With a little research, she found someone in the States who holds classes across the country. Last September, Gamboa and her cake decorator, Erika Balleza, spent two full days learning how to make four kinds of flowers. Both women took to it right away and have since created a growing demand for gelatinas in the Washington area.
"It's a pleasure to sit and make them," Gamboa says. "I get into a rhythm."
When something is deemed too beautiful to eat, as the gelatinas often are, taste can take a back seat. The ones Gamboa sells seem to be tuned to a Latino palate that likes very sweet desserts. But customers can special-order from Canela Bakery and specify the flavor and level of sugar, or sugar substitute.
