The New York Mets' first baseman has joined forces with the team's senior executive chef for a hamburger of his very own to be served at Citi Field in Queens, New York, the first time the Mets have ever introduced a food item as part of a partnership with a current player. In a nod to his "Polar Bear" nickname, Alonso, 26, has named his creation the Polar Burger. "A lot went into this, a lot of brainstorming," the self-proclaimed foodie recently told reporters, including PEOPLE. "I love food, and the biggest thing for me, when I'm in the kitchen or when I'm eating, is using simple ingredients to be able to bring out a super delicious, dynamic and great flavor to the meal." With help from Senior Executive Chef Jason Eksterowicz, Alonso crafted a Pat LaFrieda black truffle blended patty topped with New York maple spiced caramelized onions, smoked gouda, lettuce, tomato, claw sauce and a fresh-baked brioche bun, along with a side of polar spiced shaved Vidalia onions.

New York Mets All of the ingredients are sourced locally from New York state, from places like Mike's Hot Honey and Jake's Gouda Cheese, something the slugger said was of the utmost importance to him.

"I always have a beer with a burger at a ballgame… [so] I didn't want to just put this big, massive thing on a plate and just be like, 'Here you go, have fun.' We don't want people feeling like they need to have a wheelbarrow to get them back on the train or back in their car to drive home because they're too damn full."
