Why it works: Yam and maple syrup work together. They rank in the top 8% of all ingredient pairs, and 15 recipes mention both. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓

Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the oven to 425°F (220°C) and line two rimmed baking sheets with foil or parchment.
Cook the bacon in a large skillet over medium heat for about 8 minutes until crisp. Transfer to paper towels, crumble, and leave about 2 tablespoons of the fat in the pan.
Toss the yams with the olive oil, kosher salt and black pepper. Spread them in a single layer across the baking sheets and roast for about 25 minutes, turning once, until they begin to soften.
While the yams roast, add the butter to the bacon fat in the skillet over medium heat. Add the sliced onion and cook, stirring often, for about 8 minutes until soft and golden.
In a small saucepan, bring the maple syrup to a gentle simmer over medium heat and cook for about 5 minutes until slightly thickened into a glaze.
Pour the maple glaze over the roasted yams and toss to coat. Scatter the onions and crumbled bacon over the top.
Return the pans to the oven and roast for about 12 minutes more, until the yams are fork-tender and glazed.
Let rest for 5 minutes before serving.
