Salmon en Papillote with Watercress Sauce

Incredibly easy and really good!

I substituted sherry for the dry vermouth, which unfortunately didn't really work - next time I'll simpy use white wine -, and I used a shallot instead of half an onion. I also only made half the sauce, because I didn't have more mayonnaise than that, but that proved to be enough anyway. You might have watercress leftover this way (around here they come in 100 g bags), which is a plus as you can serve the salmon on a bed of watercress, but do make a simple dressing for the watercress.

I used half a sheet of baking paper per fish; they were too small to wrap the fish the way she describes, but I was able to make cute little parcels using a stapler - just be careful when you're unwrapping them, especially if kids are at the table.

Serve with new potatoes and a salad (unless you're using watercress). Or, better yet: serve with pasta with dill butter (dill, butter, salt)
