Preheat the oven to 350F. Grease four 2 or 3 inch ovenproof ramekins and place them in a large baking dish.

In a large mixing bowl, whisk together all your ingredients until smooth and combined. Pour the mixture into the four ramekins.

Boil a kettle or bring 2-4 cups of water to a boil. Pour enough boiling water into the baking dish to submerge the ramekins in about an inch of water.

Place the baking dish in the oven and bake the custard for around 30 minutes, until firm on top.

Remove from the oven and either enjoy warm or allow to cool completely. Once cooled, you can refrigerate it until chilled.
