French or German?

Many kids like a hot dog now and then. It's easy for parents to make and kids seem to get used to it. But mustard?
Lina thinks it's the French side. And the argument can be made that dijon is french. But I have always associated it with the German side. Perhaps it's just my fathers addiction to a good mustard but the kids do seems to like a little mustard.
What's your vote?

 Mustard blew the doors off of Pascal.

Louis was so interested, he picked it up....

... and tried to drink it. Just like his Babba.
