Potato Gratin with Sage

Total time: 70 minutes
    I make this in the fall when I still have fresh sage in the garden.  If you don't, dried will work.  This will be for 2 meals.

 Ingredients: 

• 4 medium potatoes, 20oz, (600gr)
• 1/2 cup (4oz, 120ml) chicken stock
• 1 cup (4oz, 120gr) Cheddar or Gruyère, either shredded or thinly sliced
• 15 - 20 fresh sage leaves or 4 tsp dried (rubbed) sage
• 1/2 cup (2oz, 60gr) fresh Parmesan

 Instructions:

• Slice potatoes as thinly as possible with a sharp knife. 
• Put 1/3 of the sliced potatoes in the bottom of small baking dish - just big enough to hold everything.
• Put 1/2 of the sage and 1/3 of the cheese on potatoes. 
• Repeat layers once. 
• Top with a layer of potatoes and final layer of cheese. 
• Pour stock over all, cover and bake (400F, 200C) for 40 minutes. 
• Remove and sprinkle with Parmesan. 
• Bake, uncovered, for 20 minutes.
