This is a great recipie. My "modification notes" are in blue below (I never follow recipies directly). It's easy to prepare. Serve it with a spinach salad and hot garlic bread.

• 4 large sweet potatoes, peeled and cut in thick slices Depends on the size of these potatoes – I only needed three!
• 2 tbsps. butter, salted
• 2 small shallots, peeled and chopped (I used green onions, finely chopped, plus garlic. What's a shallot?)
• 1/2 cup dry white wine (I used white, plus some red that we had sitting around)
• Water
• 1 small pinch of salt
• 1 bay leaf (Left bay leaf out - only had crushed, which scares me. Used sage instead)
• 11/2 cups grated Gouda (I probably used more…)
• 3 tbsps. sour cream (saved this to just prior serving)
• 2 more tbsps. butter, salted
• 4 tsps. heavy (35 per cent) cream (I used regular half-and-half coffee cream)
