I purchased mustard oil at an indian grocery here, and it's not the same thing. Mostarda, in my experience, has a wonderful horseradish-like "kick" at the end of the delightful sweet taste. This mustard oil was far too mild to provide that. I could easily put my nose to the bottle without being overwhelmed. I have also searched the web, looking for a source to mail order the Essenza di Senape, with no luck. As a matter of fact, I asked a colleague working in Milan to bring some over for me for a recent meeting, but she was nervous that she'd get in trouble with customs at the airport, and instead brought me some mustard powder, and the instructions to dissolve it in hot wine Does anyone know of any source for this, anywhere outside of italy? Unfortunately, work doesn't take me there much but it does get me to other places in Europe and the US, and I'd love to be able to make Mostarda on my own. Thanks in advance for any help you may be able to provide. Marc
