Bright, garlicky, and silky smooth, this lemon sauce punches well above its weight as a drizzle, dip, or dressing. Sunflower seeds are the star here — soaked briefly to soften them, then blended with fresh lemon juice, zest, garlic, and a whisper of cumin until the whole thing turns luxuriously creamy. It's the kind of sauce that makes you want to pour it over everything, from roasted vegetables to grain bowls to warm flatbread. For anyone navigating tree nut allergies or sensitivities, this is a genuinely satisfying alternative to tahini-style or nut-based sauces — no compromises required. The optional cayenne adds a gentle kick if you want a little heat, but the base recipe is already deeply flavorful on its own. A quick blend, a taste, a little seasoning adjustment, and you're done — it keeps in the fridge for up to four days, so you can make a batch and reach for it 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.
