Slice off the bottom of garlic head, and separate the cloves, leaving the outer covering in place. Put the cloves in a shallow 8-inch square baking dish, and drizzle with olive oil.
Bake at 350 degrees for about 20 minutes until the garlic is soft. Cool and remove the skins. In a food processor or blender, add garlic, salt, pepper and lemon juice. Process 30 seconds or until almost smooth, scraping sides occasionally. Set garlic mixture aside.
In a 3-quart saucepan, heat the vegetable stock over high heat until boiling. Add the salt and butter. Once butter has melted, slowly stir in the grits, and return to a boil. Reduce the heat and simmer 45 minutes, whisking constantly until thickened.
Remove from heat. Stir in the garlic mixture, half-and-half and cheese until creamy. Return to heat and simmer on low for an additional 5 minutes. Serve immediately. |
