Conservas De Cambados Razor Clams Recipe

Clean and Trim

Rinse razor clam meat thoroughly under cold running water to remove grit. Trim away any dark stomach or intestinal parts and discard. Pat the clams dry with paper towels and set them in a single layer on a tray.

Brine

In a bowl, dissolve 2 tablespoons coarse sea salt in 1.5 cups cold water and add the 120 ml distilled white vinegar. Submerge the clam meat in the brine and let sit 10 minutes to firm the flesh and remove residual grit. After 10 minutes, drain and rinse the clams briefly under cold water. Pat dry completely.

Prepare Aromatics

Thinly slice the garlic cloves. Strip parsley leaves from stems and roughly chop. Zest one lemon into thin strips. Measure out bay leaves, peppercorns, and chili flakes.

Warm the Oil

In a small saucepan, combine the extra-virgin olive oil (500 ml) and neutral oil (150 ml). Add the sliced garlic, bay leaves, whole peppercorns, lemon zest strips, and chili flakes. Warm the oil gently over low heat until it reaches 60–70°C (140–160°F) — the garlic should infuse and become fragrant but must not brown. Maintain this temperature for 6–8 minutes to extract flavor, then remove from heat and allow to cool slightly for 5 minutes. Remove and discard the bay leaves and lemon zest if you prefer a cleaner oil (optional).

Sterilize Jars

Wash jars and lids in hot soapy water and rinse. Place jars upright in a large pot, cover with water, add 1 tablespoon kosher salt, and bring to a simmer for 10 minutes to sterilize. Keep jars hot until ready to fill to avoid thermal shock.

Layer Clams and Aromatics

Using tongs, remove hot jars from the water and drain. Place 2–3 thin garlic slices and a pinch of chopped parsley and 1–2 peppercorns in the bottom of each jar. Neatly pack the razor clam meat into jars without compressing — leave about 1–1.5 cm headspace (approximately 1/2 inch). Add a bay leaf to each jar and, if using, a small pinch of chili flakes and a strip of lemon zest.

Pour Warm Oil

Re-warm the infused oil gently if it cooled below 50°C (122°F). Carefully pour the warm oil over the clams, using a spoon to help the oil settle between pieces and to release any trapped air bubbles. Fill so the clams are completely submerged and maintain about 0.5–1 cm headspace. Wipe jar rims with a clean cloth.

Seal

Place lids on jars and screw until fingertip-tight (do not overtighten).

Water Bath (Optional for Extended Shelf Life)

To further preserve and ensure safety, process jars in a boiling-water bath. Place filled jars upright in a pot with a rack, cover with at least 2.5 cm (1 inch) of water above the lids, and bring to a gentle boil. Process 15 minutes, then turn off heat and let jars sit in the water for 5 minutes. Remove jars carefully and place on a towel to cool undisturbed for 12–24 hours. Check seals — lids should be concave and not flex when pressed. Refrigerate any jars that did not seal properly and use within 1–2 weeks.

Maturation

Allow sealed conservas to rest for at least 48 hours before eating to let flavors meld; ideally 5–7 days. Store in a cool, dark place for up to 3 months. Once opened, keep refrigerated and consume within 5–7 days.

Serve conservas de Cambados razor clams chilled or at cool room temperature. Spoon clams and some of the aromatic oil onto crusty bread or toast, garnish with extra chopped parsley and a squeeze of lemon. Use the flavored oil for dressings or to finish grilled vegetables.
