Ingredients

• 6-8 oz (approx. 2 cups, lightly packed) fresh rock samphire, rinsed
• 1 cup white vinegar (5% acidity)
• 1 cup water
• 1 tablespoon sea salt
• 1 teaspoon granulated sugar (optional, for balance)
• 2 cloves garlic, thinly sliced
• 2 thin slices lemon
• 1 teaspoon mixed pickling spices (e.g., 1/2 tsp mustard seed, 1/4 tsp coriander seed, 1/4 tsp black peppercorns, 1 small bay leaf)
• Equipment:
  1 pint / 16-oz canning jar with lid (or similar heat-proof jar)
  Small saucepan
  Fine-mesh strainer (optional, for brine)
  Medium bowl of ice water
  Tongs
  Funnel (optional, for pouring brine)

Directions

1. Prep the Jar: Wash your jar and lid thoroughly with hot, soapy water. For extra safety, you can sterilize the jar by boiling it for 10 minutes or running it through a hot dishwasher cycle. Keep the jar hot until ready to use to prevent thermal shock when adding hot brine.
2. Prep the Samphire: Rinse the rock samphire well under cold running water. Trim off any tough, woody ends or discolored bits. You want the tender, succulent stems.
3. Blanch & Shock: Bring a small pot of water to a rolling boil. Prepare your bowl of ice water. Carefully submerge the trimmed rock samphire into the boiling water for exactly 30 seconds. Immediately remove the samphire with tongs and plunge it into the ice bath. This "shocks" the samphire, preserving its vibrant green color and crisp texture. Let it cool completely, then drain it very well. Pat dry with a clean kitchen towel.
4. Make the Brine: In your small saucepan, combine the vinegar, water, salt, and optional sugar. Bring the mixture to a rolling boil over medium-high heat, stirring until the salt (and sugar, if using) is fully dissolved. Reduce heat and simmer gently for 2 minutes to allow the flavors to meld.
5. Pack the Jar: Tightly pack the blanched and drained rock samphire into your hot, clean pint jar. Distribute the garlic slices, lemon slices, and pickling spices evenly amongst the samphire as you pack.
6. Pour & Cool: Carefully pour the hot brine over the samphire, ensuring it completely covers the greens. Use a chopstick or knife to gently dislodge any trapped air bubbles. Leave about 1/2 inch of headspace from the rim of the jar. Secure the lid tightly. Let the jar cool completely to room temperature on your counter.
7. Refrigerate & Wait: Once cool, transfer the jar to the refrigerator. The pickled rock samphire will be ready to enjoy in a minimum of 7 days, but the flavors are best developed after 2–3 weeks.
