    1/2 c  Water
      4 sm Peeled Potatoes

  A VERY QUICK AND EASY STEW RECIPE
  
  Heat the cooker.  Add shortening. Brown the meat.  Add the vegetables,
  stewed tomatoes, and water, and place over the meat.
  
  Close the cover securely.  Place pressure regulator on vent pipe and cook
  10-12 minutes with pressure regulator rocking slowly. Cool cooker at once.
  If desired, make a paste of 1 tablespoon flour and 1/4 cup of water and
  stir into stew to thicken.
  
  Another method of preparing stew is to cook the meat separately 8-10
  minutes, then add the vegetables and cook 5 more minutes with the presure
  regulator rocking slowly.
  
  My Seasoning: 1 part garlic powder, 1 part onion powder, 1/2 part black
  pepper. Mix well before measuring and adding to the recipe.
