Recipe(tried): Rapid Ajiaco Soup (pressure cooker)

RAPID AJIACO SOUP (AJIACO RAPIDO)

1-2 pounds beef cut in small squares
2 potatoes
3 malangas (root vegetable or tuber that can be bought in Spanish markets & that is better than potatoes)
3 ripe plantains
1 sweet potato or yam
1 can tomato puree (or some chopped tomatoes)
1 teaspoon garlic powder
1 teaspoon onion powder
salt and pepper to taste
1 cube beef boullion, broken up
1 cube (or equivalent powdered) ham boullion
1/4 cup of vegetable oil

In your pressure cooker, saut the beef in the oil with the salt, pepper, onion and garlic powder, for about 5 minutes, turning so the beef won't burn. Take it off the stove and add the ham bouillon, beef bouillon, tomato puree, potatoes, yams, malangas, and plantains. Fill the pressure cooker with water to full mark as indicated. Put the lid on and let it cook (following pressure cooker manufacturer's instructions) for about 20 minutes.
