INDIANAPOLIS  The Hoosier family behind last year's chocolate-covered bacon at the Indiana State Fair is at it again. Their newest offering? A burger served between two Krispy Kremes, known simply as the doughnut burger. FAT & CALORIE BOMBS: Every state has worst-for-you foods RECIPES: Healthier versions of fried chicken Veteran concessionaire Dennis Reas said that if his family wants to survive selling novelty fair food, he must think of new products every year to keep the customers coming back. "You just have to have something new to keep people entertained," said Reas, 53, as fair visitors circled his stands around lunchtime. "Every year we try to come up with something new." And it seems to be working — even if the $6.50 burger and another new offering, deep-fried butter, produced almost as many questions as orders from the first customers of the 17-day fair. Visitors can sample a hog's trough of oddball fair foods: deep-fried sushi, deep-fried dill pickles, deep-fried candy bars, chocolate-covered popcorn balls, root-beer marinated ribs and the garbage burger — a pork patty covered with pulled pork on a bun. But it was the deep-fried butter and doughnut burgers that drew the customers and the "just curious." "That's awesome," said Stacey Hine, 32, after she took the first bite of her burger topped with bacon. "Seriously, that is so good." Her mother, Debbie Hine, 55, and younger sister, Kelly Hine, 28, agreed that the sweetness of the doughnut and the saltiness of the beef made the burger a hit. The Reases, who live in the southern Indiana city of Corydon, had thought about serving the dish for years but started offering it just this winter during the Florida State Fair and other Sunshine State events, where it exploded in popularity. "It was all over YouTube and Facebook," Dennis Reas said. At the deep-fried butter stand, twin sisters Rayanna Bibbs and Rachel Bibbs, 18, and their friend Rachel Endres, 16, all from Indianapolis, quizzed operator Blake Reas about the concoction. He said he picked up the idea from a vendor at the State Fair of Texas last year. "When they say deep-fried butter, you think a butter stick," Rachel Bibbs said. But that's not what it is. Blake Reas freezes the butter and covers it in cinnamon before cutting it into cubes and frying it in something that's been at the fair for years: funnel cake batter. He's also added a secret twist he wouldn't disclose to the original Texas recipe. "It almost comes out tasting like a cinnamon roll," he said. Copyright 2010 The Associated Press.
