[originaltext]W: I’ve been reading about a new healthful snack food. It’s made

W: I’ve been reading about a new healthful snack food. It’s made from fish. Have you heard anything about it?
M: No, I haven’t. But I don’t like fish very much anyway.
W: Not to worry. Although it’s made primarily from fish, it actually doesn’t have a fishy taste. In fact it can be flavored with tomato, cheese, or chocolate for instance.
M: How could it not taste fishy? Do you know how this snack food is made?
W: First, the fish is crushed, cooked and fermented, then water and starch are added to make dough.
M: It sounds awful.
W: Actually the dough is tasteless at that point. So the flavorings are added to give it some taste.
M: Well, it still sounds a little strange. But I suppose this product will at least be low calorie and high protein, like a health food.
W: Yes, you could call it that. And it has a long shelf life, so it won’t spoil quickly. It is also easy to digest and can be made from types of fish that usually aren’t eaten or from high grade fish byproducts.
M: Mm... Have you got any samples? I might be willing to try the cheese-flavored variety.
W: No. None of these seems to be available yet. As I understand it, this fish smack food probably won’t be in the stores for another couple of years. So you have a while to get used to the whole idea.
M: A couple of years, ha? It may just take me that long, but thanks for telling me about it.
What is the conversation mainly about?
