When you remove the cover you will see that there is now a pool of liquid. Drain the vegetables in a colander.

Thoroughly rinse the vegetables with cold water, I use several changes of water. Because if you don't get the salt out at this stage then your finished relish will be too salty.

Then place the vegetables into a clean tea towel and twist to squeeze out all the excess water.

Sterilise the jars by washing, rinsing and placing in the oven at 110C for 20 minutes.

Add the vegetables to the vinegar and sugar and bring back to the boil. Then add the spice and cornflour mix and cook for 3 minutes stirring.
