She always loved to cook and feed people, and started cooking and experimenting in the kitchen at age 7. From there on, she taught herself how to make fresh pasta, sushi, smoked and grilled BBQ, homemade sauce, and much more. Jenniffer learned how to cook Nicaraguan food from family, friends, and YouTube, always adding her "sazon" to the dishes. She started with a childhood memory of the "Buñuelos" which is Yucca, cheese, and egg in a simple syrup. As she continued to experiment with Nicaraguan recipes it became a passion. Then it became a way for her to stay connected to her roots, so she started to learn about Nicaraguan cuisine and techniques. Always wanting her own business, she went all-in with La Fritanguera that opened July 10, 2017.

    Jenniffer joined the Concord Chamber in 2019 to introduce her company to the community. Her involvement has now grown to help others see the benefit of joining the Chamber.
