Bright, peppery, and vibrantly green, this blended sauce brings serious restaurant energy to a weeknight plate. Watercress gives it a bold, slightly bitter edge that pairs beautifully with the brightness of fresh lemon juice and zest, while a small clove of garlic adds just enough depth. Streaming in extra virgin olive oil while the blender runs creates a silky, emulsified texture that clings perfectly to whatever you drizzle it over. For anyone managing fructose sensitivity, sauces and condiments are often a minefield of hidden sweeteners and high-fructose ingredients — this one sidesteps all of that with a clean, whole-ingredient list you can feel confident about. The optional flat-leaf parsley nudges the flavor in a fresh, herby direction without overwhelming the watercress. It comes together in just a few minutes of blending, and a quick taste-and-adjust at the end means you can dial in the salt and lemon exactly to your liking.
