Moo's Winter Melon and Chicken Soup

This is a very light, savory Chinese soup. Moo made this often during the winter (after all it's made with winter melon). If you don't know, a winter melon looks a little like a watermelon from the outside. The flesh is a light green and cannot be eaten raw. I like to call this Chinese penicillin. It's light like chicken noodle with the winter melon providing an interesting texture. This is a palate pleaser.

6 cups chicken stock
1 lb. winter melon, cut into bite-size chunks
6 fresh shitake mushrooms, sliced
1 medium size knob of fresh ginger, minced
1 chicken breast, raw
1 clove garlic, crushed
1 tsp. sherry
1 tsp. sugar
2 tsp. soy sauce, low sodium is best
1/2 tsp. sea salt
2 tsp. olive oil

Cut flesh away from rind of winter melon. Cut flesh into chunks. Remove stems from mushrooms and slice caps. Bone raw chicken breast and cut into bite-size pieces. Mix chicken, garlic, sherry, sugar and 1/2 tsp. of the soy sauce. Let stand for 15 minutes. Mix salt, 1 1/2 tsp. of soy sauce, olive oil. Set aside. Heat stock to boiling, add melon, mushrooms and ginger and simmer for 20 minutes. Add chicken marinade mixture. Stir well. Add salt/soy/oil mixture. Cook until the chicken is tender.
