Flavoured salts are a good way of adding subtle flavours when cooking, particularly if you don’t have any of the fresh ingredient for a dish. They also look better as a condiment than boring plain salt. If you are lucky enough to get a bunch of fresh celery with plenty of leaves then save the nice darker green outer leaves and after rinsing and removing any excess water, in a salad spinner, spread them out on a baking tray and put them in the oven at about 120 degrees C / 250 F for about 10-15 mins until they dehydrate. You can turn off the oven and leave them in there to ensure that they are completely dried out. They will be dry and crisp and you can either crush them in your hands or chop them up roughly with some scissors. Then place them in a mortar and add sea salt, enough to fill a smallish jar, and pound them together. Put the salt in a sealed jar and keep in a dry place. This also makes a nice gift for a foodie friend.
