📝 About This Recipe

Hailing from the picturesque island of Sifnos, Mastelo is a masterpiece of Cycladic simplicity, traditionally prepared in a custom-made clay pot during the Easter festivities. This dish celebrates the purity of high-quality lamb or goat, perfumed with the unique aroma of fresh dill and bathed in local red wine without a drop of water. The result is fall-apart tender meat with a crisp, golden exterior and a rich, concentrated sauce that captures the essence of the Aegean.

🥗 Ingredients

The Meat

  • 2.5 kg Lamb or Goat (bone-in leg or shoulder, cut into large chunks)
  • 2 tablespoons Sea salt (coarse Greek sea salt preferred)
  • 1 tablespoon Black pepper (freshly cracked)

Aromatics and Liquid

  • 2 large bunches Fresh Dill (finely chopped, including tender stems)
  • 500 ml Dry Red Wine (a robust Greek wine like Agiorgitiko)
  • 10-12 pieces Vine twigs (cleaned and dried (traditional) or a stainless steel rack)

The Seal

  • 2 cups All-purpose flour (for the dough seal)
  • 3/4 cup Water (to mix with flour)
  • 2 sheets Parchment paper (to cover the pot)

👨‍🍳 Instructions

  1. 1

    Begin by washing the lamb pieces thoroughly with cold water. Pat them dry with paper towels; removing excess moisture is crucial for the meat to sear slightly during the long roast.

  2. 2

    In a large bowl, season the meat generously with the coarse sea salt and freshly cracked black pepper. Massage the seasoning into the meat to ensure every crevice is coated.

  3. 3

    Add the finely chopped dill to the bowl. Toss the lamb pieces vigorously so the dill adheres to the seasoned surface of the meat.

  4. 4

    Pour the red wine over the meat. Cover the bowl and let it marinate for at least 1-2 hours at room temperature, or overnight in the refrigerator for deeper flavor penetration.

  5. 5

    Prepare your 'Mastelo' (clay pot) or a heavy Dutch oven. Traditionally, vine twigs are placed in a crisscross pattern at the bottom to create a natural rack, preventing the meat from boiling in its juices.

  6. 6

    If you don't have vine twigs, place a small wire rack at the bottom of the pot. Arrange the lamb pieces carefully on top of the twigs or rack, stacking them neatly.

  7. 7

    Pour the remaining wine and dill marinade from the bowl into the bottom of the pot. Do not add any water; the meat will release its own succulent juices.

  8. 8

    Place a layer of parchment paper over the mouth of the pot, then cover with the lid. If using a traditional clay pot without a tight lid, use a second layer of parchment tied with kitchen twine.

  9. 9

    Prepare the 'louto' (seal) by mixing flour and water until a stiff dough forms. Roll it into a long rope and press it around the edge where the lid meets the pot to create an airtight seal.

  10. 10

    Preheat your oven to 150°C (300°F). Place the pot in the center of the oven and bake for 5 to 6 hours. The low temperature and long duration are the secrets to the meat's melting texture.

  11. 11

    After 5 hours, carefully crack the dough seal and remove the lid. The meat should be dark golden and pulling away from the bone.

  12. 12

    Increase the oven temperature to 200°C (400°F) and bake uncovered for another 15-20 minutes to give the top pieces a beautiful, crispy crust.

  13. 13

    Remove from the oven and let the meat rest in the pot for 15 minutes before serving. This allows the juices to redistribute, ensuring every bite is moist.

💡 Chef's Tips

Always use bone-in meat as the marrow adds incredible depth and gelatinous richness to the sauce. If you cannot find vine twigs, thick stalks of rosemary or even cinnamon sticks can provide a similar aromatic elevation for the meat. Don't skip the dough seal; it traps the steam inside, which is what tenderizes the tough fibers of the lamb without adding water. For the best results, use a high-quality dry red wine that you would actually enjoy drinking. If the lamb is very lean, you can drizzle 2-3 tablespoons of extra virgin olive oil over the top before sealing.

🍽️ Serving Suggestions

Serve with thick-cut potato wedges roasted in the same oven, seasoned with lemon and oregano. A crisp Greek salad (Horiatiki) provides a refreshing acidic contrast to the rich, fatty lamb. Pair with a glass of Xinomavro or the same Agiorgitiko used in the cooking process. Provide plenty of crusty sourdough bread to soak up the 'mastelo' juices at the bottom of the pot. A side of Greek yogurt or tzatziki can help balance the intense herbal notes of the dill.
