Guac attack! It’s all about the avocado at this cook-off

There’s only one rule at this cook-off: Don’t double-dip!

At Guactacular, hundreds of avocado lovers will get to dunk their chips in 20 different guacamole recipes from competing enthusiasts. But event organizers are making sure that the May 8 celebration stays free of any George Costanzas.

“Frito Lay is giving us hundreds of Tostitos bags, so there will be no need to dip a chip twice,” said Rachel Anderson of the blog Nachos NY, which has been running the cook-off at the Bell House for three years.

Still, you’ll want to help yourself to plenty of the avocado creations, as Guactacular competitors are known for their creative blends. For instance, last year’s winning dip featured a dollop of ricotta.

“Guacamole is a food that anyone can make and everyone thinks that they have the best recipe,” said Anderson. “I can’t say I haven’t had a guacamole I didn’t like.”

Guactacular at the Bell House [149 Seventh St. between Second and Third avenues in Gowanus, (718) 643-6510], May 8 from 5 to 8 pm. Tickets $15 in advance, $18 at the door. For info, visit www.nachosny.com.
