Welsh Rarebit - cooking recipe

Ingredients

2 tbsp butter
1 None leek, sliced
1 tsp fresh thyme leaves
1 tbsp flour
1/2 cup ale
1/4 tsp Dijon mustard
1 tsp Worcestershire sauce
1 tbsp cream

Preparation

Melt butter in a medium saucepan over medium-high heat. Saute leek and thyme leaves for 6 mins, until soft but not colored. Add flour; cook for 2 mins.
Whisk beer into leeks; stir well to remove any lumps. Add mustard, Worcestershire sauce, cream, and cheese; stir until cheese has melted. Season with salt and pepper.
Preheat the broiler to high. Place toasted sourdough on a baking sheet and spoon cheesy leek mixture over bread. Broil for 2-3 mins, until golden and bubbling. Remove from broiler and serve immediately.
