Low Iodine Strawberry Rhubarb Crumble
Tart rhubarb and sweet strawberries bubble together under a golden, coconut-laced topping that smells absolutely incredible as it bakes. The filling gets its glossy, jammy texture from arrowroot starch rather than cornstarch, and maple syrup does all the sweetening without any refined sugar in sight. What makes this dessert such a smart choice for anyone navigating iodine restrictions is how naturally the ingredient list falls into place — no dairy, no eggs, no iodized salt, and no processed additives that tend to sneak unwanted iodine into otherwise simple bakes. The crumble topping leans on cassava flour, tapioca starch, and shredded coconut for a texture that's crumbly, slightly chewy, and deeply satisfying in a way that feels nothing like a compromise. A touch of Ceylon cinnamon runs through both the filling and the topping, tying the whole dish together with warm, fragrant depth. Let it rest for a few minutes after it comes out of the oven so the filling thickens up and every scoop holds its shape beautifully on the plate.
