Mustards are made of a basic mixture of dry mustard seeds, vinegar and seasonings. They get their distinct and varying flavours from the added vinegars, wines, sugar, herbs and other seasonings. Some prefer their mustard to be a natural pale yellow or brownish shade; others add turmeric for a vivid yellow mustard.

Your mustard can be sweet to sharp, winy, biting, hot, pungent, musty or tangy depending on your personal preference.

You can add herbs such as basil, marjoram, mint, oregano, parsley, sage, thyme or rosemary. I prefer using dried herbs because they stand up better to the mustard flavour. But you can also fresh herbs. Add at least 2 tablespoons finely chopped fresh herbs to this recipe.

How To Seal and Store Your Mustards

Remember to sterilise your jars before using them. Simply pour boiling water into them, then empty and allow to dry completely. After sealing your jars keep them in a cool dark place for 1-2 weeks before using, to allow the flavours to develop. Use the mustard within 3 months. Once opened, the flavour will start to deteriorate, so refrigerate and use it up fairly quickly.

What Can Go Wrong With Your Mustard and Why?

If the mustard dries out on the surface, it has not been sealed correctly. Some of the flip top jars does not always seal tight. Cover the mouth of the jar with cling wrap before closing. If the mustard is left too long, it will lose most of its strength. If the mustard develops mould or an ‘off’ aroma you did not sterilise your jars properly.

Mustard Recipe Variations
