Here’s a dessert based on the assumption that everything tastes better with bacon—even dessert. It pays homage to my friends in Quebec (where I’ve taped my Maître du Grill TV show), offering a triple blast of maple flavor in the form of maple-glazed bacon, maple ice cream, and maple whipped cream.
Step 1: Make the candied bacon and walnuts: Place the bacon in a cold skillet over medium heat. Cook until the fat renders and the bacon begins to brown and crisp, 6 to 8 minutes, stirring with a wooden spoon. Add the walnuts and continue cooking until the bacon and walnuts are golden brown, about 2 minutes. Do not let them burn. Drain the bacon mixture by placing it in a strainer over a heatproof bowl. Save the bacon fat for a future use, like frying potatoes.
Step 2: Return the bacon and walnuts to the skillet and add the 1/2 cup of maple syrup and the vinegar. Cook the bacon mixture over medium heat until it is thick and syrupy, about 3 minutes, stirring with a wooden spoon. The mixture should have a pourable consistency. Set the skillet aside and keep warm. The candied bacon can be made earlier in the day; cover the skillet and set it aside. Rewarm the candied bacon over low heat when you are ready to serve the sundaes.
Step 3: Make the sundaes: Place the cream and 2 tablespoons of maple syrup in a chilled metal bowl and, using a mixer or whisk, beat the cream until soft peaks form. Alternatively, pour the cream and maple syrup into a CO2 charger and shake well to mix, 7 or 8 times. Invert the charger and squeeze the handle to release the whipped cream. Refrigerate the maple whipped cream, covered, until serving.
Step 4: To assemble the sundaes, scoop the ice cream into balls and place 1 scoop in each of 4 sundae glasses or bowls. Spoon the warm candied bacon and walnuts on top. Top with the maple whipped cream and a sprinkling of cinnamon.
