Sweet Pickled Watermelon Rind (Using the Part You'd Throw Away)

A sweet, spiced pickled watermelon rind recipe that turns a part almost everyone discards into a genuinely good pickle.

Sweet Pickled Watermelon Rind (Using the Part You'd Throw Away)

Watermelon rind is a part almost every home cook throws away entirely, but it pickles into a genuinely good sweet pickle, with a texture somewhere between a cucumber and a firm apple.

Sweet Pickled Watermelon Rind

Prep time: 20 minutes, plus resting | Cook time: 10 minutes | Makes: about 1 quart

Ingredients

  • 4 cups watermelon rind, dark green outer skin removed, cut into 1-inch cubes
  • 1 cup white vinegar
  • 1 cup water
  • 3/4 cup sugar
  • 1 tbsp kosher salt
  • 1 cinnamon stick
  • 4 whole cloves
  • 1 tsp whole allspice berries
  • 1 (1-inch) piece fresh ginger, sliced

Instructions

  1. Trim away the tough dark green outer skin from the watermelon rind, leaving the pale green-white flesh underneath. Cut into even 1-inch cubes.
  2. Bring a pot of water to a boil and blanch the rind cubes for 5 to 7 minutes, until just tender but not falling apart. Drain well.
  3. In a saucepan, combine the vinegar, water, sugar, salt, cinnamon stick, cloves, allspice, and ginger. Bring to a simmer, stirring until the sugar dissolves.
  4. Add the blanched rind to the brine and simmer together for 5 minutes.
  5. Transfer the rind and brine to a clean jar, making sure the rind is fully submerged.
  6. Let cool to room temperature, then seal and refrigerate.
  7. Ready to eat after about 2 days, with the flavor developing further over the following week.

Notes

Save the watermelon rind the next time you cut up a watermelon rather than composting it - this recipe uses the part between the outer skin and the pink flesh, which most people discard without a second thought.

Why This Recipe Is Worth the Extra Steps

Unlike most other pickles in this guide, watermelon rind benefits from a brief simmer in the brine rather than just a pour-over method, since the rind needs a bit more cooking to soften from its naturally quite firm, almost woody starting texture. The result is a genuinely good sweet pickle rather than a chewy, underdeveloped one.

What to Use It For

  • A sweet counterpoint alongside rich, savory dishes like barbecue or fried chicken
  • Chopped into a relish for hot dogs or sandwiches
  • Served alongside a cheese board for a sweet, spiced contrast

Variations

  • Spiced version: Add a few thin slices of fresh chili to the brine for a sweet-spicy version.
  • Citrus version: A few strips of lemon or orange peel added to the brine brighten the overall flavor.
