01 - Preheat oven to 350°F. Line a baking dish with parchment paper.
02 - Place the cored and halved apples cut side up in the prepared baking dish.
03 - Melt butter over medium heat in a small pan until it foams and turns golden brown with a nutty aroma (around 3 to 4 minutes). Remove from heat promptly.
04 - Drizzle the browned butter evenly over the apple halves.
05 - Mix walnuts, raisins, 2 tablespoons of honey, cinnamon, and a pinch of salt in a small bowl. Spoon this filling into the hollow centers of the apples.
06 - Cover the baking dish loosely with foil and bake for 20 minutes. Remove the foil and continue baking for 10 minutes more, until apples are tender and lightly caramelized.
07 - Whisk tahini, 1 tablespoon of honey, and a pinch of salt together. Gradually whisk in warm water until the sauce reaches a smooth, pourable consistency.
08 - Allow baked apples to cool slightly, then drizzle with tahini sauce and serve warm.
