A bright, tangy, and smooth rhubarb sauce that is quick and easy to make, perfect for drizzling over summer desserts like ice cream and pound cake.

Ingredients

Scale
  • 4 cups chopped rhubarb stalks (about 500g or 1.1 lbs)
  • 1 cup granulated sugar (200g)
  • 2 tablespoons freshly squeezed lemon juice
  • 1/2 cup water (120ml)
  • 1 teaspoon vanilla extract (optional)
  • Pinch of salt

Instructions

  1. Rinse 4 cups (500g) of rhubarb stalks under cold water. Trim off any leaves and chop the stalks into roughly 1-inch (2.5 cm) pieces.
  2. In a medium saucepan, combine the chopped rhubarb, 1 cup (200g) granulated sugar, 1/2 cup (120ml) water, and a pinch of salt. Stir gently to mix.
  3. Place the pan over medium heat. Once it starts to bubble, reduce heat to low and simmer gently, stirring occasionally, for 10 to 15 minutes until the rhubarb softens and the sauce thickens to a syrup-like consistency.
  4. Stir in 2 tablespoons fresh lemon juice and 1 teaspoon vanilla extract (if using). Cook for another 2 minutes.
  5. Optional: For a smoother sauce, strain the mixture through a fine mesh sieve, pressing gently to extract the liquid. Otherwise, leave it chunky.
  6. Let the sauce cool to room temperature before transferring to a clean jar or container. Store in the refrigerator for up to one week.

Notes

If the sauce is too thick after cooling, stir in a splash of water to loosen it. If too thin, simmer a few minutes longer but watch carefully to avoid burning. Fresh rhubarb is preferred over frozen for best texture and flavor. Sugar amount can be adjusted to taste or dietary needs. Variations include adding cinnamon, cloves, berries, or ginger for different flavor twists.
