If anyone wonders what happened to the tomatoes and fish sauce from last night's pesce alla marinara...
Pasta with fish sauce, sailors style, p 170. I would not make this again. As good as last night's branzino was, I found the sauce far too sweet. In general I do not enjoy cooked tomatoes, or anything really sweet, without a balancing bitterness or acidity. And, yes, apparently I have a gene for this.
Bugialli may be turning in his grave* but when no one was looking I poured red wine vinegar over it. Better, but there are still leftovers. Lemon juice might have been a further improvement but I would have had to get up off my chair. Lots of red pepper was another possibility.
*As far as I know Bugialli is not actually dead, though he does not answer his email.
