Sterilise your jar by filling it with boiling water and leaving it to stand for a few minutes.
Empty the water from the jar and drop the melons to the bottom. These will take the longest to mature.
Now add your carrots over the top.
Sprinkle a few of the celeriac leaves and stems over the top and then add your celeriac slices.
Add your red peppers and green tomatoes and sprinkle more celeriac leaves and stems.
Now add your cucumbers and, finally, your aubergines.
If you have any left, sprinkle the rest of your celeriac leaves and stems over the top.
