beef stew pressure cooker

• The pressure cooker allows me to have this beef stew on the table in less than an hour instead of the typical 2-3 hours I spend making it!
  We've eaten this beef stew three times in the past couple weeks and I never get sick of it. It's THAT good.1 pound stew beef
• 4 small carrots OR 3 large ones, cut into 1/4 inch slices
• 1 onion, diced
• 3 stalks celery, cut into whatever size pieces you like
• 3 cloves garlic, minced
• 2 russet potatoes, peeled and cut into one inch chunks
• 2 tablespoons tomato paste
• 2 bay leaves
• 1 tablespoon soy sauce
• 2 tablespoons Worcestershire sauce 
• salt, pepper and a bit of all purpose flour for coating the beef
• 4 cups chicken, vegetable, or beef stock
• whatever cooking oil you like

I'm using a Fagor Splendid 6 qt pressure cooker - it cooks at 15 psi. If you have an electric pressure cooker, you'll want to use the "high" setting.
