1. Preheat the oven to 300°F (150°C) to ensure a gentle, even cooking temperature.
2. Prepare the ramekins by placing them in a deep baking dish with enough space between them to accommodate a bain-marie.
3. Heat the heavy cream in a medium saucepan with minced garlic over medium-low heat until hot but not boiling. Remove from heat and allow to cool slightly.
4. In a large mixing bowl, whisk the egg yolks until pale and slightly thickened. Add salt, black pepper, and Parmesan cheese, whisking to combine.
5. Slowly pour the warm cream mixture into the egg yolks while whisking constantly to avoid scrambling the eggs. Continue whisking until smooth and fully combined.
6. Fold in the fresh crabmeat gently to ensure even distribution while preserving its texture. Add lemon zest if desired for a bright flavor contrast.
7. Evenly divide the crab custard mixture among the ramekins, filling each about three-quarters full.
8. Create the bain-marie by carefully pouring hot water into the baking dish until it reaches halfway up the sides of the ramekins, ensuring even cooking and preventing curdling.
9. Bake the custards in the oven for 35-45 minutes or until they are just set but still slightly wobbly in the center.
10. Remove the ramekins from the bain-marie and let them cool to room temperature. Cover and refrigerate for at least 2 hours or overnight for the flavors to meld.
11. Before serving, sprinkle an even layer of granulated sugar, brown sugar, or a mix of both onto each custard.
12. Use a kitchen torch to caramelize the sugar by moving the flame in a circular motion about 2 inches away from the surface until the sugar melts and forms a crisp, golden topping. Alternatively, place the ramekins under a broiler, keeping a close eye to avoid burning.
13. Allow the caramelized sugar to cool briefly before serving to ensure a crackly texture when broken.
14. Garnish with fresh chives, microgreens, a sprinkle of smoked paprika, or a small slice of lemon to enhance presentation and flavor.
15. Serve the Crab Brulee on individual ramekins for an elegant touch, accompanied by sides like a light citrus salad, crusty bread, or roasted vegetables, and pair with sparkling wine for a complete dining experience.
