Baker: William Teresa of Minneapolis.
From Italy, with love: During a college study-abroad year at the Università di Bologna, Teresa dated a fellow student. The couple would frequently jump on a train and visit her family in Cesena, a small city in Emilia-Romagna, happily immersing themselves in the cooking lives of his girlfriend's parents and grandparents. "They were so lovely," Teresa said. "I learned to make pasta with them. We'd spend hours making dough, and laughing. It was wonderful to be in a place where food is so rooted in tradition and place, and to encounter something that has always been made by the same people, with little variation."
The takeway: One of the grandmothers baked a chewy-crispy and outrageously rich almond cookie, which the family enjoyed with espresso. Teresa was instantly smitten. Unfortunately, the cookie's recipe didn't return to the United States with him. "She was wary of sharing a family recipe," he said. "That's their pride."
Diligence: After doing his research, Teresa stumbled upon a similar-sounding sweet. "Ricciarelli," he said. "They're from Siena, in Tuscany, and not that far from Bologna." He began to tweak the formula (less sugar, for starters), and as each iteration inched closer to the unassuming-looking cookie of his memory, he became confident that he'd hit replication pay dirt. "Since then, I've probably made them a hundred times," he said. "They're not like any other American cookie. Maybe that's why so many people ask me for the recipe."
Judges' raves: "And we have our winner," was one immediate response. "You think it's going to be like a Russian tea cake, but it's so much better," said another. "That's a cookie I'd bake every year," added a third.
Dietary surprise: Among its many appealing virtues — it's a very easy recipe to pull together, for example — this is a gluten-free cookie.
Have faith: "I never think that one egg white is going to make the dough wet enough to hold together," Teresa said. "But it does. You have to trust it."
Watch closely: To preserve the cookie's exceptional texture, overbaking is a definite no-no. "You have to watch them," Teresa said. "When the cracks start to form, and you see the very slightest hint that they're turning brown, that's when you pull them out of the oven. Otherwise, they'll turn rock hard an hour later."
