Place squash halves cut side down in a baking dish. Fill the dish with water to the depth of 1/4 inch. Bake 40 minutes in the preheated oven.
Remove squash from oven, and set the oven to broil. Turn squash cut side up in the dish, and season lightly with salt. Place 1 teaspoon butter and 1 1/2 tablespoons apricot preserves in each squash half. Return to oven, and broil 5 minutes, or until butter is melted and squash is lightly browned.
