Season chicken with salt, black pepper and achiote/recado powder on both sides. Sear chicken pieces in a large dutch oven for 2 mins on each side. Work in batches, do not overcrowd the pan. You want to brown them well for color. Reserve chicken pieces.
Add the celery, onion, red bell pepper and garlic to the pan with a tablespoon of olive oil. Sauté for a few minutes. Add the flour and stir, then add the chicken stock, stir and scrape all the browned bits off the bottom of the pan. The flour will thicken or tighten the liquids. Add all the seasonings, herbs and bay leaves, except the achiote paste.Â
Dissolve the achiote paste in a measuring cup with some of the hot liquid from the pot. Add it back to the pot once dissolved. Â Alternatively, you can disolve the achiote paste by scaping it through a sieve in the pot liquids as seen below. Taste for salt and add accordingly.
Add in the chicken back to the pot, cover and simmer for 1 to 1.5 hours. You can also place it oven at 350 degrees (better way).
Remove the habanero pepper and bay leaves. Shred the chicken.
