Pickled Ash Keys

Subscribe to my newsletter to get updated when new recipes are released.

Ash Keys (Fraxinus excelsior) provide a unique taste sensation. If you’re into Slow Food then this is certainly a slow recipe as it takes three months before you can indulge your taste buds.

One thing to make sure is that you pick your Ash Keys when they are very young, and the small seed within the ‘wing’ has barely developed. You can see the seed if you hold the Ash Key up to the sunlight.

  • 2 cups of Ash Keys without stalks
  • 1 tsp ground cloves
  • 1 tsp ground cinnamon
  • 4 bay leaves
  • 8 peppercorns
  • 1 tsp allspice
  • 1/2 tsp ground ginger
  • 1 tsp salt
  • 3 tbsp brown sugar
  • 2 cups cider vinegar
  • water

Suggested Instructions

  1. Wash your Ash Keys, then place in a pan covered with cold water and bring to the boil. Simmer for 5 minutes.
  2. Strain off the water and return to the pan with some fresh water, then bring back to boil and simmer a further 5 minutes.
  3. Drain off the water again, allow to ‘dry’ slightly and then pack into warm dry jars, but allow an inch of space from the top of the jar.
  4. Put the spices, salt and sugar into a bowl and add the vinegar.
  5. Put the bowl into a saucepan (cover it), add some water (not to the bowl but just into the pan) and bring slowly to the boil. I’ve never been very good at this so my one splutters and bubbles furiously, even when its on simmer. I’m sure there’s some scientific reason, but as I failed miserably at science I don’t have an answer. Allow to gently boil for about 5 minutes, then remove the bowl and let it sit for about 4 hours or until it is cold.
  6. Strain the liquid through a muslin or sieve into a jug and pour over the Ash Keys filling the jars right to the brim.
  7. Screw on the tops or better yet use the kind of jars I have in the picture above.
  8. Store for 3 months and let the pickle ‘mature’.
  9. Give your friends a shock when you serve this up as an after dinner treat, along with some fine cheese.

My Latest Book is Now Available on Amazon as a Paperback or Kindle

For over fifteen years I have experimented and explored the world of wild plants. Uncovering how our ancestors used plants to nourish and heal themselves.

I’ve spent thousands of hours digging through scientific papers, read hundreds of books. Even gone so far as to be nomadic for over a year. During this time I followed the seasons and plants around the highways and byways of these isles.

I have written this book to help you rediscover our forgotten plant heritage. To learn how to use wild plants as food and medicine. Knowledge that was once common to everyone. Click here to learn more.

  1. i’ve searched but haven’t found any other way of using these keys…do you know of any other site i could research?

  2. Not sure if it counts as foraging but Ash for firewood has a couple of lines in a poem on the subject
    “Ash tree dry or ash tree green
    Makes a fire fit for a queen”
    Its true too – our sycamore needs at least a years seasoning but ash burns right away. (Only branches that have fallen off…)

  3. Thanks for the info. I probably won’t make these as ash trees are hard to find in my neck of the woods but I love food history and folklore.

  4. Hi Robin
    I made a batch a couple of weeks ago and they are fermenting madly! Liquid leaking out of the Kilner jars and bubbling furiously. What should I do now?

  5. Hi –
    If you want to avoid the “spluttering”, perhaps you could sit the bowl on the pan with a knife (or some other bit of cutlery) between the edge of the pan and the bowl. This should stop the steam building up to the point where the only option it has to escape is to lift the bowl.
