📝 About This Recipe

Tracing its lineage back to the Roman Empire, Pecorino Romano is a bold, salty, and sharp sheep's milk cheese that serves as the backbone of Roman cuisine. This traditional recipe captures the essence of the 'Ager Romanus,' utilizing high-quality ewe's milk and a specific thermophilic culture to create that signature crystalline texture and piquant finish. Making this cheese is a labor of love, a slow transformation of simple milk into a complex, aged masterpiece that defines the flavors of Italy.

🥗 Ingredients

The Milk Base

  • 2 gallons Sheep's Milk (Full fat, non-ultrapasteurized; goat milk can be substituted but will change flavor profile)
  • 1/2 teaspoon Calcium Chloride (Diluted in 1/4 cup non-chlorinated water)

Cultures and Coagulants

  • 1/4 teaspoon Thermophilic Starter Culture (Type C) (Contains S. thermophilus and L. bulgaricus)
  • 1/2 teaspoon Liquid Animal Rennet (Diluted in 1/4 cup cool, non-chlorinated water)
  • 1/8 teaspoon Lipase Powder (Italase) (Dissolved in 1/4 cup water 20 mins prior to use for that signature 'sharp' kick)

Brining and Finishing

  • 2 cups Non-iodized Sea Salt (For the brine bath)
  • 1/2 gallon Filtered Water (For the brine)
  • 1/2 cup Coarse Sea Salt (For dry salting during aging)
  • 2 tablespoons Extra Virgin Olive Oil (For rubbing the rind during the later stages of aging)

👨‍🍳 Instructions

  1. 1

    In a large stainless steel heavy-bottomed pot, slowly heat the sheep's milk to 90°F (32°C). Use a gentle heat to avoid scorching the bottom.

  2. 2

    Add the diluted Calcium Chloride and the Lipase solution. Stir thoroughly using an up-and-down motion for 1 minute.

  3. 3

    Sprinkle the Thermophilic culture over the surface of the milk. Let it rehydrate for 2 minutes, then stir gently to incorporate. Cover and let the milk ripen for 45 minutes, maintaining the 90°F temperature.

  4. 4

    Add the diluted rennet. Stir with an up-and-down motion for exactly 1 minute, then use your spoon to 'still' the milk so it stops moving. Cover and let sit for 30-45 minutes until a 'clean break' is achieved (the curd should split cleanly when lifted with a knife).

  5. 5

    Cut the curds into tiny, rice-sized grains (about 1/8 inch). This small cut is essential for the dry, hard texture of Pecorino. Let the curds rest for 5 minutes.

  6. 6

    Slowly increase the heat to 118°F (48°C) over a period of 45 minutes. Stir constantly but gently to prevent the curds from matting together. This 'cooking' phase expels the whey.

  7. 7

    Once the target temperature is reached, continue stirring for another 15 minutes. The curds should feel firm and springy, like the texture of cooked egg whites.

  8. 8

    Allow the curds to settle to the bottom of the pot for 10 minutes. Drain the whey until it reaches the level of the curds.

  9. 9

    Line a cheese mold with sanitized muslin or cheesecloth. Transfer the curds into the mold, pressing down firmly with your hands to remove air pockets.

  10. 10

    Press the cheese at 10 lbs for 30 minutes. Remove, flip, and re-wrap. Increase pressure to 25 lbs for 2 hours. Flip and re-wrap again, then press at 50 lbs for 12 hours (overnight) at room temperature.

  11. 11

    Prepare a saturated brine by mixing the 2 cups of salt with 1/2 gallon of water. Submerge the cheese in the brine for 8 hours per pound of cheese, flipping halfway through.

  12. 12

    Remove from brine and pat dry. Place the cheese in an aging 'cave' (a cool, humid environment at 55°F and 80-85% humidity). For the first 30 days, dry salt the surface once a week, brushing off excess.

  13. 13

    After 2 months, rub the rind with a light coating of olive oil to prevent excessive cracking. Age for a total of 5 to 8 months, flipping twice a week. The longer it ages, the sharper and more granular it becomes.

💡 Chef's Tips

Always use non-chlorinated water; chlorine kills the delicate cheese cultures. If you cannot find sheep's milk, use the highest quality raw cow's milk and double the lipase powder for a similar bite. Maintain strict humidity during aging; if the cheese cracks too deeply, the humidity is too low. Ensure all equipment is sanitized with a food-grade sanitizer to prevent 'late blowing' or unwanted mold growth. Don't discard the whey! Use it to make fresh Ricotta immediately after the curds are removed.

🍽️ Serving Suggestions

Grate freshly over a classic Tonnarelli Cacio e Pepe for the ultimate Roman experience. Serve in rustic chunks alongside a bowl of broad beans (fava) and a glass of crisp Frascati wine. Drizzle with dark, chestnut honey to balance the intense saltiness of an extra-aged wheel. Pair with a bold, tannic red wine like a Brunello di Montalcino or a Sagrantino di Montefalco. Shave over a fresh arugula and lemon salad to add a savory, umami punch.
