  1. Dissolve the salt in about 4 litres of water. Put the onions or quartered shallots, tomatoes and cauliflower in a large bowl and cover with the salted water. Cover with cling film and keep in the fridge or a cool place for 24 hrs.

  2. Drain the vegetables in a colander and tip them into a large preserving pan or flameproof dish. Add the cucumber and capers, and cover with 2 litres of fresh water. Bring to the boil and cook for 10 mins. Drain the vegetables and tip into a large bowl.

  3. Melt the butter in a saucepan, then add the flour and stir well to make a roux. Slowly add the vinegar, stirring all the time, and cook for a few mins until thickened. Add the sugar, turmeric and mustard powder, and season with black pepper. Pour over the vegetables and stir to combine. Pack the vegetables into sterilised jars (see tip below) and seal.

  4. Leave in the fridge for at least 5 days before eating, so that the vegetables can absorb all the mustardy flavours. Will keep in the fridge for 6 weeks.

Can this be made & left to mature like chutney?

Just made a batch ready for the festivities and it's looking OK. Agree that you need a bit more flour than recipe states and I used standard malt vinegar and its not as yellow as I hoped so would be better to use the distilled stuff.

Sorry....I even added 25g flour to the 125g butter!!! :-)

Have just made a batch of this mustard pickle, but had to have a few attempts at the "sauce". I added the 25g flour to the 125g flour, but as I added the vingear, it split, so I wondered, as I'd written the recipe into my own recipe book, I thought I'd written the flour to butter ratio incorrectly for the roux, so then did 125g of butter and flour....wrong! Far too thick! Starting to feel a bit like goldilocks, I decided to make a regular roux (equal flour to butter 25g each) and alas it worked!!!

Not sure if it was a typo in the recipe or if in a few weeks I'm going to have awful pickle!!! Has anyone else tried this? Usually there are comments to help when I go wrong!!!Happy Christmas everyone :-)
