Mousseline au Gratin

Total time: 50 minutes
    This is an interesting change from the usual mashed potatoes. More similar to a mousse, it's light and airy, and a lovely golden brown from the sprinkling of cheese.

 Ingredients:

• 2 medium potatoes, 12oz 360gr
• 3 cloves garlic
• 1/4 tsp salt
• 1 egg
• 1 tbs olive oil
• 3 tbs Parmesan cheese
• pinch nutmeg
• water

 Instructions:

• Bring a saucepan half full of water to a boil over medium heat.  Add salt to water. 
• Peel potatoes and garlic. 
• Cut potatoes into large chunks, garlic into small chunks. 
• Add potatoes and garlic to water, cover and bring to a boil. 
• Partially remove lid and boil until done, 15 - 20 minutes. 
• When done, drain, reserving cooking water. 
• Mash potatoes and garlic together. 
• Add enough of the cooking liquid to make very soft mashed potatoes, 1 - 2 tbs.  
• In a medium bowl whisk egg, 2 tsp oil, pinch of nutmeg and 1 tbs Parmesan. 
• Add 1 tbs of hot cooking water and whisk well. 
• Stir into potatoes.  The potatoes will be thick but very soft, almost pourable. 
• Lightly oil a 1 quart glass baking dish. 
• Spoon/pour the potato mixture in. 
• Sprinkle remaining Parmesan over the top. 
• Drizzle with remaining oil and bake, 400F (200C) for 20 minutes. It will puff up and turn golden.  Serve.
