Mumu: Papua New Guinea’s Traditional Earth-Oven Feast

Introduction

Mumu is the quintessential communal dish of Papua New Guinea, cooked in an earth oven much like its Pacific cousins. The word “mumu” refers both to the method—heating stones in a pit—and the festive meal that emerges. Traditionally held for celebrations, weddings, and gatherings, a mumu is as much about coming together as it is about the food itself.

At its heart, the mumu is a layered spectacle of meat, root crops, and leafy greens, all wrapped in banana or ti leaves and slow–cooked over glowing stones buried in the earth. Pigs were the traditional centerpiece, but modern interpretations often include chicken, beef, or a combination of proteins. Over hours of steaming, each ingredient absorbs the smoky, mineral-rich essence of the heated stones.

The aroma of a mumu—earthy smoke mingled with coconut and ginger—is impossible to replicate in a conventional kitchen. It’s a dish that commands patience and respect for ancient cooking methods. In villages, the entire process—from fire-building to pit-digging—is a communal ritual, reflecting the deep connection between people, land, and food in Papua New Guinean culture.

Beyond its cultural roots, mumu also showcases the lush bounty of Papua New Guinea’s highlands and coastal regions. Starchy staples like sweet potato (kaukau), taro, and cassava form the base layers, while green leafy vegetables, coconut milk, and local spices round out the flavors. Every mouthful is a testament to the island’s agricultural richness and the artistry of its cooks.

Today, mumu continues to be honored at festivals, markets, and family celebrations. Although building an earth oven may seem daunting, home cooks can adapt the technique using a Dutch oven or covered grill, capturing the essence of this time-honored tradition in their own backyard.

Why You Should Make Mumu

1. A True Taste of Papua New Guinea: Cooking a mumu brings the authentic flavors and techniques of Papua New Guinea into your home. You’ll experience the smoky aroma of heated stones and the complex layering of meats and root crops that define this island feast.

2. A Communal, Hands-On Celebration: Preparing a mumu is more than cooking; it’s a shared ritual. Gathering friends and family to help dig the pit, heat the stones, and assemble the bundles transforms meal preparation into a memorable social event.

3. Nutritionally Balanced and Wholesome: Mumu combines lean proteins with fiber-rich tubers and nutrient-packed greens. Slow steaming preserves vitamins and minerals, and the inclusion of coconut milk adds healthy fats, making mumu both delicious and nourishing.

4. Adaptable for Modern Kitchens: While a traditional pit is ideal, you can achieve excellent results using a Dutch oven, covered charcoal grill, or even a slow cooker. This flexibility means you can enjoy the essence of mumu without needing extensive outdoor equipment.

Ingredients for Mumu

Meats (Choose 1–2):

• 1 whole pig (for large gatherings)

• OR 4–6 chicken quarters

• OR 2 lbs beef chunks

Tubers & Roots:

• 4 large sweet potatoes (kaukau), scrubbed

• 4 taro roots (peeled and halved)

• 4 cassava (yuca) pieces, peeled and cut

Vegetables & Greens:

• 2 large bunches leafy greens (e.g., cabbage, spinach, or local greens)

• 4–6 corncobs, husks removed

Seasonings & Flavorings:

• 2 cups coconut milk

• 2 tablespoons grated ginger

• 4 cloves garlic, minced

• 2–3 fresh chilies, sliced (optional)

• Salt to taste

Other Essentials:

• Banana or ti leaves (for wrapping)

• Hot stones (or substitute: fire‑heated bricks or well‑heated lava rocks)

• Soil or sand (to cover the pit)

Step-by-Step Instructions

Traditional Earth-Oven Method

1. Dig the Pit: Choose a well‑ventilated outdoor area. Dig a pit about 2–3 feet deep and wide enough for your ingredients and stones.

   
   

2. Heat the Stones: Build a large fire in the pit using hardwood logs. Once the logs have burned down to red‑hot embers, add volcanic stones or fire‑bricks and let them heat for 1–2 hours.

3. Prepare the Wrappings: While the stones heat, wash and pat dry banana or ti leaves. Blanch them in hot water for 30 seconds to make them pliable.

4. Layer the Ingredients: On a large banana leaf, arrange the tubers and roots first (sweet potatoes, taro, cassava). Drizzle with coconut milk, sprinkle with ginger, garlic, chilies, and salt. Top with the meat pieces, then a layer of corn kernels and leafy greens. Fold the leaf into a tight parcel and tie with kitchen twine. Repeat until all ingredients are prepared.

5. Load the Pit: Using tongs or a shovel, remove the burned-out ashes, leaving the hot stones. Place the wrapped bundles directly on the stones in a single layer. If space allows, stack another layer of bundles on top.

6. Cover and Seal: Place more hot stones over the bundles, then cover everything with damp burlap or clean cloth, followed by soil or sand to trap the steam.

7. Cook Low and Slow: Allow the mumu to cook for 3–4 hours. The slow steaming extracts rich flavors and renders the meat tender.

8. Uncover and Serve: Carefully remove the soil, cloth, and stones. Lift out the parcels, unwrap, and transfer the contents to serving platters.

Modern Kitchen Adaptation

If building an earth oven isn’t feasible, you can approximate the mumu method indoors:

• Dutch Oven: Layer ingredients in a large Dutch oven just as above. Cover with lid, then wrap the pot in foil. Bake at 325°F (160°C) for 3 hours.

• Covered Grill/Smoker: Heat charcoal or wood chips until glowing, then place parcels on the grill rack away from direct flames. Cover and cook for 3–4 hours, replenishing coals as needed.

• Slow Cooker: Layer ingredients in a slow cooker, seal tightly, and cook on Low for 6–8 hours. Finish by uncovering and giving the final 30 minutes on High to reduce excess liquid.
