The salmon at Pike Place Fish varies whether it's wild or farm raised. Right now they have wild caught smoked king from Alaska but I know at other times it has been farm raised in British Columbia by Creative Salmon Co. Last week the traditional was wild but the pepper/garlic was farmed.

I always look at the sticker on the back of the vacuum pack- it says whether it's wild or not. I doubt either seller lied to you though. Probably just a different shipment.

I saw fresh horseradish down at Pike Place Market this morning. I think it was at Frank's, but probably at the other high stalls as well.

El Mercado Latino, located in Post Alley at Pike Place Market between Pike and Pine St sells a frozen puree and also a Brazilian passion-fruit concentrate/puree in 500mL bottles.
