Preheat your oven to 325°F and lightly grease a 6-inch oven-safe baking dish or large ramekin with a touch of oil.
In a medium mixing bowl, whisk together the ricotta cheese, Greek yogurt, egg, vanilla extract, lemon zest, sea salt, and half of the honey until the mixture is completely smooth.
In a separate small bowl, use a fork to mash the fresh raspberries with the remaining half of the honey until it forms a thick, jam-like consistency.
Pour the ricotta batter into the prepared baking dish, smoothing the top with a spatula.
Drop small spoonfuls of the raspberry mixture onto the surface of the cheesecake batter.
Use a toothpick or the tip of a knife to gently swirl the raspberry sauce into the batter, creating a marbled pattern.
Bake for 35 to 40 minutes, or until the edges are golden and set, but the center still has a slight jiggle.
Remove from the oven and let it cool to room temperature, then refrigerate for at least 2 hours to allow the cheesecake to firm up before serving.
