Method:
Slice one end off of each lemon and save the end.
Scoop out the pulp.
If the lemon will not stand upright, with the open end up, cut a thin
slice off the other end to level it.
Peel the cucumber and chop it
coarsely.
Combine the diced abalone and cucumber with the grated
radish, rice vinegar, sugar and soy sauce.
Season with salt.
Toss
well, then stuff into the lemons.
Cover them with their "lids" and
serve on small saucers.
