Place the ramekins into a large, oven-proof baking dish. Evenly distribute the custard between the ramekins, filling them about three-quarters full.
Next, fill the baking dish with very hot water until the water rises about half way up the ramekins. This will create a bain marie, which will cook the custards more evenly. For more information on this, watch the end of Step 1 of the
Crème Brulee Recipe. Carefully transfer to the oven, making sure you don't get any water inside the ramekins.
Let the custards bake for approximately 35 to 40 minutes or until they are just set but still jiggle in the center (like in
Step 2 of this Creme Brulee). If some are done before the others, remove them from the bain marie and transfer them to a cooling rack.
