Caramelize sugar in a heavy skillet. Transfer while hot to the bottom of a buttered 1-1/2 quart casserole or mold, or to 4 to 6 individual baking dishes. Sprinkle pecans on top of caramelized sugar.

Blend remaining ingredients together in an electric blender; or whip the eggs first, then add both kinds of milk and vanilla. Pour gently into the prepared mod or dishes. Set the baking dish or dishes in a shallow layer of water in another pan.

Bake at 350 degrees for about 1 hour, until firm. Serve warm or cold on a dollup of chocolate sauce.
