Peel onions. Cut bottoms flat but leave core to hold the onion together. Cut onions in wedges, ¾ of the way down, leaving a star design on the top. Force onions to blossom slightly by resting them in very cold water for a few minutes. Place in oiled, deep baking dish, sized to hold the onions snugly together.

Drizzle 1 tbsp roast beef drippings down center of each onion. Add 1 tbsp butter on the top and press slightly into the center.

In a bowl, whisk together white wine or beef stock or beer and cornstarch or flour. Pour gently over onions in baking dish. Sprinkle lightly with salt, pepper and Grains of Paradise. Cover tightly and roast at 350 degrees for 45 minutes. Test for doneness and continue roasting if necessary, checking at 10 minute intervals for doneness.
