It'll be guac and roll at the Bell House next month

Last year’s Guactacular was such an unexpected success, the organizers ran out of chips.

And one of the concoctions caught the CLAP (though named by its component parts: cilantro, lime, avocado and, get ready, pomegranate).

The good news is that the organizers are certain things will go better this year when the all-guac cooking competition returns to the Bell House on May 5 — Cinco de Mayo.

Sure, amateur cooks who think they have a great guac are welcome to join in the fun, but this year, there are limits to creativity where avocados are involved.

“I’m really hopeful someone doesn’t sneak mayonnaise in. That’s appalling,” said Lee Frank, a Flatbush resident who, as one of the founders of the food blog NachosNY.com, is somewhat of a guac expert.

And this year, there are top-flight judges including Jessica Amason of “This Is Why You’re Fat.”

To help add to the festivities, Alex Meixner, a Grammy-nominated Mexican polka player, will be on hand for some high-energy, romp-shaking tunes.

As for those chips?

“We have 50 bags,” said Frank confidently.

Sounds like it won’t be enough again.
