Not sure if I will even try it but if I do it will be outside. Since the store bought is less strong than home grown and I guess when you add the vinegar it neutralizes it some we should be safe.
The hot mustard has tumeric listed as an ingredient so I will need that too.
We bought some liverwurst from the grocery yesterday and I sure missed the mustard. The wurst was pretty bad compared to the German meat market we use or even Aldi has much better for half the price.
