Heat 3 tablespoons of olive oil in a heavy pot or Dutch oven over medium heat. Add the onion and cook gently, stirring occasionally, until completely softened and beginning to turn golden, about 10 to 12 minutes. Add the fennel seeds, anise seeds and cumin and cook for one minute until fragrant. The spices should bloom in the oil and become clearly aromatic.
Add the charred meat chunks and any bones to the pot. Pour in the wine and honey and stir to combine, scraping up any bits from the bottom of the pot. Add the rinsed lentils. Pour in enough water or stock to cover everything generously, 2 to 3 cups depending on your pot. Bring to a gentle boil, then reduce to a low simmer. Cover and cook for 1.5 to 2 hours, stirring occasionally, until the meat is completely tender and falling apart and the lentils have dissolved into the broth creating a thick, deeply savoury stew. The lentils should not remain distinct. They should break down into the liquid and thicken everything around the meat.
Remove and discard the bones. Taste and adjust salt. The honey should be present as a background sweetness. The anise and fennel should be clearly detectable but integrated rather than dominant.
