It may, but I only became aware of its existence when I first encountered this recipe. And someplace I frequent happened to have it a short while back, although, naturally, no one did when I went to look for it. So, having struck out, I opted to use the pickled sorrel and carefully monitor the salt levels so the dish wouldn't turn out as salty as it did four years ago when I did this the first time.
Ironically, after hunting all over green markets in Cleveland and Columbus while away before my dinner, I struck out completely. Only an hour before my flight back home I had lunch with a friend and mentioned my plight. Wouldn't you know, he had sorrel growing in his garden and would have brought it had he only known. Alas.
