OK, so here’s my survey. I was in Boston, I had a little free time, so I picked up the Restaurant Guide in the hotel and started to call seafood restaurants. (Granted, that’s not a random group of restaurants.) I asked to speak to the chef or the manager, and I posed the question “What is scrod?”
The first two restaurants I called agreed mostly with Doug’s answer: scrod is young cod or small cod under about 2 or 2.5 lbs. One chef said that there used to be a term schod to refer to young haddock, but that’s fallen out of use, and some restaurants use scrod to refer to young/small haddock.
So far, so good. Then we went to eat at Legal Seafood, so I asked the same question. Their answer (on a little handout sheet called “Fish Facts”) was: “Scrod is the generic term for any mild white fish at or near market size of 2-2.5 lbs. We use COD as our “scrod” because of its local tradition, quality, and ability to be prepared a number of ways. It is by far the most popular fish species.”
OK, that would seem to support Motorgirl’s notion that scrod (at least in Boston) can be any white fish.
However, later, in the airport, I saw a copy of the cookbook put out by Legal Seafood – and that cookbook disagrees with their “Fish Fact” sheet. Their cookbook says that scrod is cod, period.
Now, I grant you, three restaurants does not constitute a valid survey. This is anecdotal rather than factual. But the impression I have is that restaurants serve small-sized (young) cod (or haddock) as “scrod” … but they THINK that other restaurants will serve anything.
My son thinks (in hindsight) that I asked the wrong question. I should have asked, “What is scrod? what do YOU serve as scrod? What do you think other restaurants serve as scrod?” But, this insight came too late.
If someone in Boston would like to do a more thorough survey, they are welcome to it. Again, merely saying that “everyone knows” doesn’t do it. “Everyone knows” that the Great Wall of China is the only man-made object to be seen from the moon, don’t make it so. If you can verify that every restaurant chef knows… OK, then we can talk.
