I started this right after I picked 2 daikons and 3 wasabi's to see how they are doing. All were overheated for several weeks. Holy crapola those are evil! Basically it tastes like my sushi wasabi powder.
It all went into the dehydrator. The roots were peeled and sliced fine, the leaves rough cut, the stems diced up. I think they are all going to be excellent, different niches for them though.
Since I have a
thread here on permies on
Making substitutes for sushi nori because I can't grow seaweed, hey! Now I have a substitute for the wasabi! YAY!! Weird homegrown sushi stuff works for me.
I have planted more of all of these, and still have stuff out in the gardens, please keep coming up with odd ways to preserve radishes!
I think the only normal thing I might do with them is make bread and butter pickles. I used to like them, then all of the commercial ones I tried were too sweet, the recipes were tweaked as people started wanting higher levels of sweetness. Someone told me the other day he had a recipe for b&b pickles that was not gooey sweet. I think daikons would do that well.
