Peel and rinse the plantain. Cut in half and let sit in cold water.
Wash and pat the meat dry.
Salt the meat and let sit 10 minutes.
Heat up vegetable oil in a large pot. Add in the meat. Cook until the meat brown.
(optional) Bring a small pan to a very high temperature. Add in the pebe, rondelles, quatre cotés, djansang and white pepper. Toast them.
Remove the meat and set aside.
In a mixer, add in the basil, leek, celery, garlic, ginger, tomato, 4 cotés (or cloves) and toasted seeds. Blend until smooth.
In the same large pot, add in the plantain, half of the blended mix, salt and cover in water. Cover and cook for 45 minutes.
Add in the meat, the remaining blended mix, palm oil and bouquet garni. Cover and cook another 60 minutes, until both the meat and plantain are tender.
Stir occasionally to avoid burning and salt to taste.
