* Cooking quality cedar planks can be purchased in a lot of foodie stores, but you can get a cheap one at any lumber shop that stocks cedar. Just make sure its a) fairly thin and b) is not treated at all. We don't want any chemicals leaching into your fish. Strictly untreated cedar, folks.
** I like something reminiscent of Dijon but almost any kind of mustard will do here, save for yellow French's, which I do love but just doesn't hit the right notes for this recipe.
*** Lingonberry jelly can be bought at IKEA, currant jelly at most grocery stores. I have also used raspberry jam in a pinch. The trick is to get something lightly sweet with a good level of tartness.
**** Sorry friends, no subs here. I mean, you can use dried tarragon if you need to. But parsley in place of tarragon is a non-starter.
