Pardon me, would you have any Grey Poupon?

This afternoon I met Giorgia for coffee. She has set up an impromptu office in a cafe in cow square. When I arrived I was hungry, so I ordered some bitterballen, a typical Dutch snack. It is minced meat and starch (maybe mashed potatoes, maybe flour, not quite sure) that is mixed into a goo then covered in breadcrumbs and fried, then typically served with mustard. A tasty snack.

Anyway, I ordered some and they came with some Dijon mustard, and other two unidentifiable sauces, one that looked like purple caviar, the other like wasabi. So I enquired, and they both turned out to be mustards. The purple one was made from grapes and was sweet, while the green one was mixed with herbs. Both delicious. I asked the waitress what they were called and where I could find them. She talked with one of the cooks, then came back with two jars. I thought she was going to just copy the names down, but she told me I could keep them! The purple one (Moutarde au Mout de Raisin) is almost a kilo and practically full and the green one (Verte aux 3 Herbes) is about a third of the size. I was so surprised that I kept on asking if she was sure if I could keep them (of course I will share them with Giorgia). Yum!
