PITTSBURGH and CHICAGO — Heinz Mayochup sauce, the delicious blend of mayonnaise and ketchup that divided the Internet earlier this year, is officially making its U.S. debut, and Heinz is letting America decide who gets the first taste.

Through Tuesday, September 18, condiment lovers can vote on which city will get to try Heinz Mayochup before the product hits store shelves this month. The city with the most votes on Twitter.com/HeinzKetchup_US will be rewarded with a food truck takeover, complete with free samples of Heinz Mayochup…and, of course, fries for dipping.

“After seeing the unprecedented passion surrounding this product, including the nearly one million votes on social media and 500,000 votes in favor of bringing it stateside, launching Mayochup in the U.S. was a no-brainer,” said Nicole Kulwicki, director of marketing for Heinz. “We’re excited to officially welcome Heinz Mayochup sauce to the Heinz family of products, including ketchup, mustard, BBQ sauce and our most recent addition, Heinz mayonnaise.”

In the running to receive a first taste of Heinz Mayochup are the three cities whose residents were most passionate on social media about bringing Mayochup stateside earlier this year: Culver City (CA), Chicago and Brooklyn. Fans will also be able to cast their vote for a city of their choice. The city that receives the most votes will experience a Heinz Mayochup food truck takeover.

Heinz Mayochup combines the taste of mayonnaise, ketchup and a special blend of spices. Available in 16.5 oz. squeeze bottles at a suggested retail price of $3.49, Heinz Mayochup can be purchased at most major retailers including Walmart.com.
