Preheat your oven to 325°F (160°C).
In a mixing bowl, whisk together the eggs, Erythritol, and a pinch of salt until well combined.
Stir in the heavy cream, unsweetened almond milk, and vanilla extract until the mixture is smooth.
Strain the custard mixture through a fine-mesh sieve to ensure a silky texture.
Carefully pour the custard mixture into the caramel-coated ramekins or custard cups.
Place the ramekins in a deep baking dish and add hot water to the dish, creating a water bath. The water should come about halfway up the sides of the ramekins.
Cover the baking dish with foil.
Bake in the preheated oven for 35-40 minutes or until the custard is set but still slightly jiggly in the center.
Remove the custard cups from the water bath and let them cool to room temperature.
Refrigerate for at least 3 hours or overnight.
To serve, run a knife around the edges of each custard, place a plate over the top, and invert to release the caramel.
Serve cold, optionally garnished with edible flowers.
