It comes in a little carton said to contain two servings.
The ingredient list looked okay, a little high on the sodium.

I fixed it per the instructions on the carton. Despite
the sodium number on the box, it tasted like it was a
low-sodium product.

I've had some excellent cream of mushroom soup in my
life. The best was in the cafeteria at IBM Almaden,
which despite being an employee cafeteria serves food
worthy of a decent restaurant. That's what I think of
when I think of cream of mushroom soup. I just mention
that to show I don't hate mushrooms or mushroom soup.
Properly made mushroom soup is wonderful.

The Trader Joe's soup is the exact opposite of that.
Horrible soup. Very strong mushroom flavor, but an
unpleasant flavor. I suspect it was due to the use
of "natural mushroom flavor base" and "natural
mushroom concentrate", ingredients 3 and 4 after
water and mushrooms.

It reminds me of their truffle and black mushroom
flatbread frozen product. That's a flatbread covered
with cheese and fungus pieces. I reviewed that some
time ago, and it was horrible in the same way.
I haven't looked at the ingredients on that product
recently, but I wouldn't be surprised if it had
the same awful mushroom flavorings. Even though I've
eaten some bread washed down with non-alcoholic beer,
I can still taste the aftertaste from the soup.
Awful, awful soup.
