Bright, tangy, and surprisingly creamy, this sunflower seed sauce is the kind of versatile condiment that earns a permanent spot in your fridge rotation. Carrageenan — a thickener and emulsifier derived from seaweed — sneaks into a shocking number of store-bought sauces, dressings, and dairy alternatives, making label-reading feel like a part-time job. This recipe sidesteps all of that entirely, achieving its silky, pourable texture the old-fashioned way: soaking raw sunflower seeds until they're soft, then blending them high and fast with fresh lemon juice, garlic, and a drizzle of olive oil. The result is genuinely smooth and rich without a single additive or stabilizer in sight. A pinch of cumin adds warmth and depth, while the optional cayenne gives it just enough of a kick to keep things interesting. It comes together in a blender with minimal prep, and the sauce keeps well in the fridge for up to four days, so you can drizzle it over grain bowls, roasted vegetables, or wraps all week long.

Place the sunflower seeds in the blender or food processor and cover with cold water by at least 1 inch. Let soak for 30 minutes, then drain and rinse thoroughly under cold running water.
Add the drained sunflower seeds, 1/2 cup fresh water, lemon juice, lemon zest, garlic, olive oil, salt, cumin, and cayenne (if using) to the blender. Blend on high for 60–90 seconds until completely smooth and creamy, scraping down the sides once halfway through.
