Spam is not something you think of in terms of crunch, which makes Lauren Robertson’s accomplishment worth noting.

Robertson, a North Carolina resident, invented Hawaiian Spam Crackle, winning this year’s Hormel Foods Great American Spam Championship and a trip to Hawaii for this weekend’s 15th annual Waikiki Spam Jam.

The crackle is a mashup of sweet and savory — saltine crackers layered with Hot & Spicy Spam, macadamia nuts, coffee and toffee. It will be served at the Spam Jam alongside many other luncheon meat creations.

The annual celebration of all things Spam is expected to draw 25,000 people to Kalakaua Avenue for food and entertainment. The event runs from 4 to 10 p.m. Admission is free. Proceeds generated from booth sales go to the Hawaii Foodbank and other charities, including the Waikiki Community Center and the Visitor Aloha Society.
