   Butter one side of bread slices. On a baking sheet set 4 inches from heat broil both side of bread until toasted lightly. Rub buttered side of each toast with garlic. Arrange 4 toasts, garlic side up, on a baking sheet and divide pickle and corned beef among them. Top beef with onion mixture and cheese and broil under broiler about 4 inches from heat until cheese is melted. Top sandwiches with remaining toasts, garlic side down, and halve.

   In a kettle combine beef with cold water to cover by 2 inches and bring water just to a boil, skimming froth. Simmer beef, covered, 3 hours, or until tender. Remove kettle from heat and let beef stand in cooking liquid 20 minutes. Transfer beef to work surface and trim fat. Use beef as part of a boiled dinner and/or for making corned beef on rye and/or corned beef hash. Corned beef keeps, covered and chilled, 4 days.
