Low Iodine Plum & Coconut Crumble
Juicy, jammy plums bubbling up through a golden, coconut-scented topping — this crumble is the kind of dessert that makes a whole kitchen smell incredible. Managing iodine intake often means scrutinizing packaged sweets for dairy, certain food dyes, and iodized salt, so a from-scratch bake like this one is a genuinely satisfying solution. Every ingredient here — ripe plums, honey, coconut oil, cassava flour, tapioca starch, and shredded coconut — keeps things naturally low in iodine without any complicated substitutions. The sea salt called for is fine sea salt rather than iodized table salt, which is exactly the kind of small but important detail that makes this recipe work for the diet. Arrowroot starch and a splash of lemon juice help the filling thicken into a glossy, spiced sauce, while the crumble topping bakes up with satisfying crunch and toasty coconut flavor. Letting it rest for ten minutes after it comes out of the oven is worth the wait — the filling tightens up beautifully and makes every scoop clean and luscious. It's the rare treat that feels genuinely indulgent while ticking every box you need it to.
