i make coconut sorbet quite a bit and i do think its rather tasty compared to most I've tried. i'd have to scale it down but the sugar is probably 20-22% of the total liquid. The liquid is roughly 60% coconut milk and the rest water. So if your machine can handle 1 quart it would be like 1/4 quart of sugar. This sounds like a lot but its you need quite a bit of sugar to cream the sorbet. Feel free to cut the sugar a little bit, but if you do it too much then you will experience iciness. You can throw in some coconut flakes for texture. Its nice and smooth plus a heavy coconut flavor. So for the most part its just mixing the coconut milk, warm water, and some superfine sugar then putting it into your maker. You might need to chill it first depending on your machine. And this sorbet won't last long. With anything made in an ice cream machine and in a home freezer I'd give it a week then its no good. I'm a bit of a coconut fanatic. My family in the Philippines still farms them along with mangoes, pineapples, and kalamansi. There's nothing better than climbing up a tree then taking your machete to smack some coconuts open. The worst drink I've ever had was coconut wine. I thought I was going to die. But I don't think coconut water or young coconut is ideal for making ice cream or sorbet, they just don't have the body for it.
