Spinach a la Rhine

½ Tbsp. diced onion        

            Salt and pepper

½ Tbsp. fat              

3 ½ Tbsps. grated cheese

1 qt. spinach                                  

3 eggs

1 Tbsp. flour

Cook the onion in the fat, add the spinach, which has been washed and diced, and fry quickly. Add flour, to make a roux, then add milk, and cook until it thickens. Season with salt and pepper and add the grated cheese. When it starts to boil remove from the fire and add well-beaten egg-whites, then the beaten yolks, turn into a baking-dish and bake in a very hot oven (450-500 F.) for ten minutes. Garnish with shrimps.
