Grainy Rosemary Mustard

I have just bottled some Grainy Rosemary Mustard that I have made today. It is quite nice now, but give it a couple of months and the rosemary will have permeated the mustard and made a really delicious flavour.
This is a really easy recipe requiring some overnight soaking of crushed mustard seeds and finely chopped rosemary in cider or white wine vinegar and then adding a little mustard powder, flour, oil, salt and pepper today. So easy, so quick. It is great spread over a piece of beef you are going to roast or mixed with honey and oil and drizzled over some vegetables to be roasted. Great for Christmas hamper gifts too.
