Horseradish

Does anyone know where I can either find horseradish sauce (like the horsey sauce at Arby’s mixed with mayonnaise) or the actual root which is grated and mixed with vinegar and sugar. It is similar to the wasabi root Japanese use, but I need the real thing.

Thanks

ps…I will duplicate this post in the where can I find thread just incase.

I’ve seen English horseradish sauce in City Super, I believe. That’s the supermarket in the basement of the Far Eastern Mall at the bottom of Dunhua South Road.
Never seen the actual fresh stuff, though.

Jasons at the 101 Building also carries some Horseradish in jars, made by Colemans of Norwich in the UK, it is proper kosher to.

Wellman’s has it (prepared); I bought some 3 days ago to make cocktail sauce. Wellcomes have wasabi powder, which is related. I’m going to experiment with subtituting that, too.
