Carefully remove 1-2 ramekins to provide some extra room. Pour in hot water for water bath until water is about 1/2-inch deep in baking dish. Replace ramekins. (If using one large open baking dish, be sure that the dish is tall enough to accommodate the water necessary.)
Ladle mixture into ramekins.
Note: If the water level does not reach 3/4 of the way up the sides of the ramekins, carefully pour more water in.
