Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.

In a large mixing bowl, combine the plain flour, icing sugar, baking powder, desiccated coconut, and salt.

Add grated unsalted butter to the dry mixture and blend until it resembles coarse crumbs.

Mix together lime juice, lime zest, coconut milk, and milk; then pour into dry ingredients and stir until a sticky dough forms.

Lightly flour your work surface and shape the dough into a 1-inch thick disk.

Cut the disk into 8 equal triangles with a sharp knife.

Place cut scones onto the baking tray, brush tops with thickened cream, and bake for 16-18 minutes.

Allow to cool slightly on a wire rack; mix icing sugar with lime juice and drizzle over warm scones.
