NEW YORK - Andrew Martinez was not born into a New York bagel empire and didn't start baking the Big Apple's quintessential ring of doughy goodness until he was in his 40s.
Yet the Queens-born Martinez, his wife Ashley Dikos and their growing business, Bo's Bagels, are regularly mentioned among the top producers of the ring-shaped bread products, a breakfast and lunch staple.
For Martinez, his ascent into the bagel elite is a happy accident.
"Sometimes I walk in here and say, 'I can't believe this is my life,'" Martinez told AFP. "This is New York. It's incredibly difficult to succeed here."
Martinez's unexpected road to the bagel big leagues began in 2014 when the longtime restaurant industry professional found himself stuck in the hospital for two months, nourished with a feeding tube.
Martinez decided the first thing he would do when healthy again was to eat a classically delectable New York bagel, with its crusty exterior and dense, chewy interior.
But upon returning to his Harlem home, he realized there were no decent bagel shops within walking distance.
Annoyed at needing to take the subway to get his fix, Martinez began researching the bread. Bagels, he learned, originally arrived in New York's Jewish neighborhoods on the Lower East Side thanks to Polish immigrants.
Reading whatever he could find about the boil-and-bake process and picking the brains of experts, Martinez experimented for about six months before producing something resembling the bagels of his youth.
"People eat with their memories," he said. "I was dreaming about the bagels I ate when I was a kid in Queens, and that's the flavour I was looking for."
His culinary quest began to expand, however, when Martinez served the bagels to family members who urged him and Dikos to think bigger.
Small-scale catering morphed first into a farmers market stall; then in 2017 the couple opened Bo's Bagels -- a 110-square-metre retail space on a corner of 116th Street in West Harlem near several African restaurants.
Consumers have lined up at the door from the start, but the couple admits the journey has included some comical missteps.
Before their first farmers market weekend, Martinez and Dikos converted their kitchen into a production factory, putting hundreds of unbaked bagels in the refrigerator the night before.
But after a two-hour nap, they awoke to find a growing, yeast-fueled ball had popped the fridge door open.
"It was just one giant blob of dough," recalled Dikos.
The couple were forced to postpone their market debut, instead working well into the night to cut the ruined dough into pieces small enough to fit in the trash chute without raising the suspicions of apartment staff.
Creating great bagels begins about 48 hours before baking, when flour, yeast and water are combined and set out overnight.
Other key steps include an overnight refrigeration to slow the fermentation process and a 10- to 12-minute boil.
Not all New York bagelmakers go through this painstaking process -- and it shows, industry experts say.
"There are a lot of mediocre bagels," said Sam Silverman, chief executive of the trade group BagelUp.
Silverman nonetheless considers this a golden era for bagels, with legacy names such as Ess-a-Bagel and Utopia Bagels jostling with newcomers, like Bo's, who fill a surprising number of "bagel deserts" across the city's five boroughs.
