Low Iodine Mango Coconut Crumble
Juicy tropical fruit meets a golden, coconut-laced topping in this warm, bubbling crumble that feels like pure sunshine in a baking dish. Ripe mango is tossed with arrowroot starch, a squeeze of fresh lime, and a whisper of Ceylon cinnamon before it goes into the oven, where it transforms into a glossy, fragrant filling that practically begs to be scooped. The crumble itself is built from cassava flour, tapioca starch, and shredded coconut worked together with solid coconut oil and maple syrup — no butter, no dairy, no iodized salt — just coarse, clumpy crumbs that bake up beautifully crisp at the edges. For anyone navigating a low-iodine protocol, dessert is often the hardest category to crack, but this one sidesteps the usual problem ingredients entirely without sacrificing any of the comfort or indulgence you're craving. A drizzle of coconut cream over the top right before serving takes it from weeknight treat to something that genuinely feels special. Let it rest just a few minutes out of the oven so the filling tightens up, then dig in while it's still warm.
