3. Oha Demi-Glacé  4. Bone Marrow Jus

INGREDIENTS:

For the Steak:

• 5 beef sirloin or ribeye steaks (180–200g each) 
• 1 tsp ground smoked ehuru 
• Salt & black pepper, to taste 
• 2 tbsp neutral oil 
• 1 tbsp butter 
• 2 sprigs fresh thyme  – 2 garlic cloves, crushed

Potato Fondant:

• 5 large waxy potatoes (Yukon Gold or Irish potatoes preferred) 
• 3 tbsp unsalted butter 
• 1 tbsp vegetable oil (helps prevent butter from burning) 
• 1½ cups chicken or vegetable stock (hot) 
• 3 garlic cloves (crushed) 
• 2 sprigs fresh thyme 
• 1 sprig rosemary (optional)  – Salt and freshly cracked black pepper to taste

For the Oha Demi-Glacé:

• 2 tbsp unsalted butter
• 1 tbsp vegetable oil
• 2 tbsp finely chopped shallots (or mild onions) 
• 1 clove garlic, minced
• 1 tbsp finely chopped celery
• 1 tbsp finely chopped carrots
• 1 tsp tomato paste
• 1 cup palm wine
• 2½ cups rich brown beef or veal stock
• ½ tsp cracked uziza seeds or ground black pepper
• ½ tsp smoked ehuru (calabash nutmeg), optional for aroma
• 1 handful fresh Oha leaves* (rinsed, finely chiffonade)  – Salt to taste

For the Bone Marrow Jus:

• 2 large beef marrow bones, roasted 
• 1 tbsp tomato paste 
• 1 small onion, diced 
• 1 cup beef stock 
• 1 tbsp red wine
• Salt & black pepper, to taste  – 1 tsp soy sauce (to finish)

METHOD:

1. Prep & Cook the Steak:

• Pat steaks dry and season with salt, pepper, and ground ehuru. 
• Heat oil in a heavy pan until hot. Sear steaks 2–3 mins per side for medium-rare. 
• Add butter, garlic, and thyme. Baste with the butter for 1 min. 
• Remove and rest for 5–8 mins.

Potato Fondant:

• Peel potatoes and cut each into thick cylinders (about 2 inches tall). You can use a round cutter for uniform shape. 
• Rinse in cold water to remove excess starch, then pat completely dry with paper towels.
• In a non-stick or stainless-steel skillet, heat oil and 2 tbsp butter over medium-high heat. 
• Place potatoes flat-side down and sear for 5–6 minutes until golden brown. 
• Carefully flip and sear the other side for another 4–5 minutes. 
• Reduce heat to medium-low. Add garlic, thyme, and remaining 1 tbsp butter. 
• Gently pour in hot stock — it should come halfway up the potatoes (not fully submerged). 
• Season lightly with salt and pepper.
• Transfer the entire pan to a preheated oven at 180°C (350°F). 
• Bake uncovered for 30–35 minutes or until potatoes are fork-tender and most of the liquid is absorbed. 
• Baste occasionally with the butter-stock mix while baking.
• Gently remove potatoes using a slotted spoon.  – Serve golden side up.

Oha Demi-Glacé:

• In a saucepan over medium heat, melt butter with the oil. – Add chopped shallots, garlic, celery, and carrots. 
• Sauté gently (without browning) for about 5–7 minutes until soft and translucent. This creates the aromatic base for the sauce.
• Stir in tomato paste and cook for 2 mins to caramelize slightly. 
• Add palm wine and reduce by half. 
• Stir occasionally to avoid sticking.
• Pour in the beef stock and bring to a light boil. 
• Add uziza and ehuru. Lower the heat and simmer uncovered for 30–40 minutes, until reduced by about half (you should be left with a silky, slightly thickened sauce).
• Just before the reduction is ready, add the chiffonade Oha leaves and simmer for 3–5 minutes. You want the flavor to infuse, not overcook the leaves. 
• Season to taste with salt. 
• For a refined texture, strain through a fine sieve or chinois into a clean pan. 
• If you prefer texture in your plating, leave the Oha leaves in.  – Keep warm or gently reheat when ready to serve.

Bone Marrow Jus:

• Roast marrow bones at 200°C for 15 mins. 
• Sauté onion and tomato paste in a saucepan. 
• Scoop marrow into the pan, add stock and wine. Reduce until glossy.  – Season and finish with a splash of soy sauce. Strain for smoothness.

PLATING:

• Plate the steak at the center. Place potato fondant beside it. 
• Spoon over Oha demi-glacé and drizzle with bone marrow jus. 
• Garnish with micro herbs, Sautéed Carrot, or any greens for freshness.
