Hot Ham And Cheese With A Secret

• For the Horseradish Sauce
• 3/4 cup mayonnaise
• 1 tablespoon(s) prepared or fresh-grated horseradish
• 1/4 cup sour cream
• Kosher salt
• For the Sandwich
• 1 tablespoon cream, milk or club soda
• 2 tablespoon(s) Horseradish Cream Sauce
• 1 fluffy hamburger bun, split
• 2 ounce(s) thick-sliced ham
• 1 thick (1/4") slice Swiss cheese

1. For the Horseradish Sauce: In a medium bowl, stir together mayonnaise, horseradish and sour cream. Add a pinch of salt and taste, adding additional salt if desired. Makes 1 cup. Set aside at room temperature during use, then store leftovers covered in the refrigerator for up to two weeks. The sauce goes well with beef, too.
2. For the Sandwich: Mix one tablespoon of horseradish sauce with one tablespoon of cream, milk or club soda. Stir until smooth. Spread onto the cut sides of the bun.
3. Heat a small skillet over medium-high heat. Place bun halves, cut-side down, in skillet and cook until deep golden brown, rotating bun frequently to insure even browning. Remove bun from pan and place, cut-side up, on a serving plate. Place cheese on the bottom of the bun.
4. Add ham to skillet and heat it through. When hot, place it on top of the cheese. Dollop with the remaining tablespoon of horseradish sauce and the top of the bun; serve immediately.
