Place the beef in a heavy pot with 2 cups water or stock and the bouillon powder. Bring to a simmer, cover, and cook for 40 to 50 minutes until tender.
Blend the peanuts with 1 1/2 cups water or stock until very smooth, adding a little more liquid if needed.
Finish the Ndolé:
Heat the oil in a separate large pot. Cook the onion for 6 minutes, then add the garlic, ginger, and white pepper for 1 minute.
Stir in the peanut mixture and simmer gently for 15 minutes, stirring often. Add the cooked beef with its broth, the bitterleaf, habanero, and salt.
Simmer uncovered for 15 minutes until thick. Add the shrimp and cook for 4 to 5 minutes, just until opaque. Remove the whole chile before serving if used.
Notes
Peanut sauce scorches easily; stir frequently and keep the heat moderate.
The finished stew should be thick enough to mound on a spoon, not soupy.
