The Heart of Tunisian Hospitality: Couscous Osban
Couscous, a staple across North Africa, holds a special place in Tunisian culinary traditions. More than just a dish, it’s a symbol of gathering, celebration, and the warmth of shared meals. Among its many variations, Couscous Osban stands out as a true testament to Tunisian ingenuity and a beloved delicacy. This hearty and flavorful dish, often reserved for special occasions like Eid al-Adha or weddings, embodies the rich history and vibrant culture of Tunisia.
The origins of couscous itself are ancient, with evidence suggesting its existence in North Africa dating back centuries, possibly even millennia. The Berber people are often credited with its invention, transforming humble semolina into the light, fluffy grains we know today through a process of steaming. Over time, as empires rose and fell and trade routes crisscrossed the region, couscous evolved, adapting to local ingredients and culinary preferences. Each country, and even each region within Tunisia, developed its unique take on this versatile grain.
Osban, the star component of this particular couscous dish, is a type of savory sausage or haggis, traditionally made from offal (lungs, liver, heart) mixed with rice, herbs, and spices, all encased in a cleaned animal stomach. This practice of utilizing every part of an animal reflects a deep-seated respect for resources and a culinary philosophy of “waste not, want not.” While the idea of offal might seem daunting to some, the careful preparation and blend of aromatic spices transform it into a surprisingly delicious and deeply satisfying component.
The combination of fluffy couscous with the rich, savory Osban, often simmered in a vibrant tomato-based sauce with vegetables, creates a symphony of flavors and textures. It’s a dish that tells a story of resilience, resourcefulness, and a profound connection to the land and its bounty. Preparing Couscous Osban is often a labor of love, a communal effort that brings families together in the kitchen, passing down traditions from one generation to the next.
Couscous Osban: A Step-by-Step Guide
Here’s how to create this iconic Tunisian dish in your own kitchen:
Ingredients:
For the Osban:
- 1 large lamb or beef stomach, thoroughly cleaned
- 500g mixed lamb or beef offal (lungs, liver, heart), finely diced
- 1 cup short-grain rice, rinsed
- 1 large onion, finely chopped
- 1 cup fresh parsley, finely chopped
- 1 cup fresh cilantro, finely chopped
- 1/2 cup fresh mint, finely chopped
- 4 cloves garlic, minced
- 2 tbsp tomato paste
- 1 tbsp harissa (or to taste)
- 1 tbsp ground coriander
- 1 tbsp ground caraway
- 1 tsp turmeric
- 1 tsp red chili powder (optional)
- Salt and black pepper to taste
- Olive oil
For the Couscous and Sauce:
- 500g medium-grain couscous
- 2 tbsp olive oil
- 1 large onion, chopped
- 4 cloves garlic, minced
- 3-4 ripe tomatoes, grated or 1 can (400g) crushed tomatoes
- 2 tbsp tomato paste
- 1 tbsp harissa (or to taste)
- 1 tbsp ground coriander
- 1 tbsp ground caraway
- 1 tsp turmeric
- 1 tsp red chili powder (optional)
- Water or vegetable broth
- Assorted vegetables: 2 carrots, peeled and cut into large chunks; 2 potatoes, peeled and quartered; 1 zucchini, cut into large chunks; 1-2 green bell peppers, deseeded and quartered; 1 cup chickpeas, pre-soaked and cooked (or canned)
Instructions:
Step 1: Prepare the Osban Filling
In a large bowl, combine the diced offal, rinsed rice, chopped onion, parsley, cilantro, and mint. Add the minced garlic, tomato paste, harissa, coriander, caraway, turmeric, chili powder (if using), salt, pepper, and a generous drizzle of olive oil. Mix all ingredients thoroughly by hand until well combined.
Step 2: Stuff the Osban
Carefully open the cleaned lamb or beef stomach. Fill it with the prepared mixture, making sure not to overfill as the rice will expand during cooking. Leave some space at the top.
Step 3: Seal the Osban
Sew the opening of the stomach closed using kitchen twine and a large needle, forming a tight, secure pouch. You can also tie it tightly with twine. Prick the Osban several times with a fork to allow steam to escape during cooking.
Step 4: Prepare the Couscous Pot (Couscoussier)
Heat olive oil in the bottom pot of a couscoussier (or a large heavy-bottomed pot). Sauté the chopped onion until softened. Add the minced garlic and cook for another minute until fragrant.
Step 5: Build the Sauce
Add the grated tomatoes (or crushed tomatoes), tomato paste, harissa, coriander, caraway, turmeric, and chili powder (if using) to the pot. Stir well and cook for 5-7 minutes, allowing the flavors to meld.
Step 6: Add Liquids and Osban
Pour in enough water or broth to cover the Osban generously. Bring to a boil, then carefully lower the stuffed Osban into the simmering sauce. Reduce heat to low, cover, and let it simmer for at least 2-3 hours, or until the Osban is tender.
Step 7: Prepare the Couscous
While the Osban is simmering, prepare your couscous. In a large bowl, place the couscous grains. Drizzle with a little olive oil and rub between your palms to separate the grains. Gradually add about 1 cup of warm water, sprinkling it over the couscous and continuing to fluff with your fingers.
Step 8: Steam the Couscous
Once the Osban has cooked for about 2 hours, place the damp couscous into the top steamer basket of the couscoussier. Ensure the holes are not blocked. Place the steamer basket over the simmering sauce with the Osban. Cook for about 20-30 minutes, or until the steam rises through the couscous.
Step 9: Add Vegetables to the Sauce
About 45 minutes before the Osban is fully cooked (and after the first steaming of couscous), add the harder vegetables like carrots and potatoes to the sauce. Add the chickpeas at this stage too.
Step 10: Second Steaming of Couscous
Remove the couscous from the steamer basket and transfer it back to the large bowl. Break up any clumps with a fork. Sprinkle with another 1/2 to 1 cup of warm water (or a ladleful of the hot sauce from the pot) and a pinch of salt. Fluff again. Return the couscous to the steamer basket and steam for another 20 minutes.
