Place onion, garlic, ginger root, turmeric and red pepper in blender and a drop of olive oil (just enough to moisten). Cover and blend until smooth, 1 minutes. Heat oil in dutch oven, then pour blender mixture into oil (may spatter a bit). Cover and simmer for 15 minutes. Add remaining ingredients, boil. Reduce heat, cover & simmer 1 1/2 hours. Serve over rice.
