Prepare the Matumbo: Ensure your 2 lbs (approx. 900g) Matumbo is thoroughly cleaned and cut into bite-sized pieces. Pat it dry with a paper towel.

Sauté in the Pot: Set your Instant Pot or pressure cooker to the "Sauté" function. Add 1 tbsp cooking oil and heat. Add the 2 large onions, finely chopped, and cook until soft and translucent, about 5 minutes. Stir in the 4 cloves garlic, minced, and 1 inch piece of ginger, grated, and sauté for another minute until fragrant.

Add Tripe and Spices: Add the prepared Matumbo pieces to the pot. Cook for 2-3 minutes, stirring to coat with the aromatics. Add the 1 tsp turmeric powder, 1 tsp paprika, and 1/2 tsp black pepper. Stir well.
1 tsp turmeric powder, 1 tsp paprika, 1/2 tsp black pepper
Pressure Cook: Add the 3 large ripe tomatoes, chopped, 1 bell pepper, diced, and the 1/2 cup (120ml) beef or vegetable broth. If using an Instant Pot, add the additional 1/4 cup (60ml) water. Stir everything together. Close the lid and set the valve to the "Sealing" position. Select the "Manual" or "Pressure Cook" function and set the time for 40-50 minutes on high pressure. The total time will vary depending on the tripe's thickness and age. A good starting point is 45 minutes.

Release Pressure: Once the cooking cycle is complete, let the pressure release naturally for 10 minutes, then carefully turn the valve to "Venting" to release any remaining steam.
Final Touches: Open the lid. The Matumbo should be very tender. Stir the stew. If the sauce is too thin, you can set the pot to the "Sauté" function and simmer for a few minutes to reduce it.Add 1 table spoon Worchestershire for 10 minutes. Taste and adjust seasoning with 1/2 tsp salt or to your liking. Garnish with 1/4 cup (60ml) fresh cilantro, chopped, and serve hot.
