Trim the thick outer fat from the oxtail, then season the oxtail with the steak seasoning.
Pressure cooker: When cooking is complete, turn off Keep Warm and let the pressure release naturally (about 20 minutes). If your Instant Pot has a release setting, choose Natural Release; otherwise, leave the valve on Sealing. Open the lid only after the float valve has dropped completely, then skim any visible fat.
Stovetop: simmer covered over low heat for 2½ to 3 hours, until tender.
Stovetop pressure cooker: add enough water that it won't cook dry, and cook until tender.
Meanwhile Prep the other Ingredients
While the oxtail comes to pressure, make the dumpling dough (see my Guyanese Duff recipe) and set it aside to rest.
Peel and prep your veggies. If using fresh cassava peel and cut into 1.5 inch chunks. Peel the sweet potatoes and plantains and cut into 1 1/2 inch pieces. Then soak in water so they don't dry out or brown.
Start the Soup Base
When the Instant Pot cycle completes and is in its Natural Release stage, start the soup base. AAdd the cassava, corn, the remaining onion, garlic, and thyme, and 1 tsp salt to a large, deep pot. Pour in just enough water to cover the cassava and corn. Cover the pot and bring to a boil over high heat (about 10 minutes), then cook for 5 minutes.
If you’re using frozen cassava and it comes in large chunks, cook it for 5 minutes first (it’s easier to cut once softened), then lift the chunks out, carefully remove the inner vein with a fork, cut into manageable pieces, and return them to the pot.
Drain the sweet potatoes, then add them to the pot with the cassava. Add more water if needed, enough to cover the provisions with room to boil. Then add in the onion powder and garlic powder to season it.
Bring it Together
When the cassava and sweet potatoes are fork-tender, add the plantains and keep cooking until tender. Some of the provisions will melt into the broth, and that's what you want.
At this point the oxtail should be ready. Remove the thyme stems from both pots. Add the tender oxtail and all of its broth to the pot with the ground provisions, then stir in the wiri wiri peppers and more salt if needed. Reduce the heat to medium.
Add the Dumplings
Shape the rested dumpling dough (made during prep; see my Guyanese Duff recipe) into tablespoon-size dumplings (round, or strips like spinners). They'll swell as they cook.
For light, fluffy dumplings, drop them on top of the soup without stirring. Cover, reduce the heat to low, and steam for 10 minutes, then gently stir them in. For dense, chewy dumplings, stir them into the broth as you add them.
Taste, adjust the salt, and serve hot.
Notes
Don't fill your pressure cooker more than ⅔ full. Pressure time stays the same if you scale the recipe.
This makes 8 hearty servings, enough for a family of 5 with leftovers, the way Caribbean soup is meant to be made. Leftovers taste even better the next day. The recipe halves easily if you're cooking for fewer people (keep the pressure cooking time the same), or just make the full batch and freeze half for a gloomy day.
For a paleo version, skip the split peas and dumplings and thicken with pumpkin or eddoes. If you're gluten-free like me, make the dumplings with gluten-free all-purpose flour.
