Cooking Methods
Preparation Steps
- Gather and measure all the ingredients.
- Place your ramekins or custard cups in a deep baking dish.
- Separate 4 egg yolks in a small bowl.
Cooking Instruction
- In a medium saucepan, heat the heavy cream over medium heat until it just starts to simmer. Remove from heat and set aside.
- Then in a mixing bowl, whisk the egg yolks, keto sweetener, vanilla extract, and salt until fully combined.
- Slowly pour the warm cream into the egg mixture, whisking constantly to avoid cooking the eggs.
- Once combined, strain the mixture through a fine mesh sieve to remove any egg solids (optional for an ultra-smooth custard).
- Pour the custard mixture into the prepared ramekins.
- Fill the baking dish with hot water until it reaches halfway up the sides of the ramekins.
- Bake for 30-35 minutes or until the custards are set around the edges but still slightly jiggly in the center.
- Remove from the oven and let the custards cool in the water bath for 10 minutes, then transfer to a wire rack to cool completely.
