The Quirky Foodster Team

Ingredients
- Whole pig (approx. 20–25 kg / 44–55 lb), cleaned and prepared — 1
- Sea salt, to season generously
- Banana leaves, for lining and covering
- River stones, for heating (or heat-safe rocks)

Method
- Dig a pit large enough to hold the pig and heat a generous layer of stones over a large fire until very hot.
- Season the cleaned pig generously with sea salt, inside and out.
- Line the bottom of the heated pit with some of the hot stones, then a layer of banana leaves.
- Place the pig on top, then place a few more hot stones inside the body cavity if the size allows.
- Cover the pig with more banana leaves, then a final layer of hot stones.
- Cover the entire pit with earth or a heavy tarp to seal in the heat and steam.
- Leave to cook undisturbed for 4–6 hours, depending on the size of the pig, until the meat is fully tender.
- Carefully uncover, remove the banana leaves, and carve to serve the gathered community.
Introduction: A whole pig slow-cooked in a traditional underground earth oven, the centrepiece of major Marshallese celebrations and community feasts.
Cultural Background: The ‘um’ earth oven method — heating stones in a pit, then covering food to cook slowly under earth and leaves — is a technique shared across much of the Pacific, and in the Marshall Islands it remains the way a whole pig is prepared for weddings, church celebrations and other major community gatherings.
Tips: Getting the stones hot enough is critical — a large, sustained fire beforehand ensures even, thorough cooking. This is traditionally a communal effort; enlist help for digging, heating stones and carving.
Variations: Smaller cuts of pork can be cooked using the same earth oven method for a scaled-down version. Wrap additional root vegetables like breadfruit or taro alongside the pig to cook in the same pit.
Storage: Refrigerate leftover meat in an airtight container for up to 3 days.
Reheating: Reheat gently, covered, in an oven at 150°C (300°F) with a splash of water, until warmed through, to avoid drying out.
