Heat oven to broil. Have serving tray ready with crackers, lemon and brandy. Cut cheese into 3 wedges; arrange in star shape in a pie pan or shallow quiche pan suitable for broiling and serving. Pour melted butter over cheese. Broil 4 to 6 inches from heat until cheese is bubbly and light brown. Add to serving tray and take to guests. Pour slightly warmed brandy over cheese and ignite immediately, in front of guests. Squeeze lemon juice over cheese to extinguish flame. Serve at once with firm crackers, toasted pita bread or crusty French bread slices.
