Lemon washing up liquid

You'll need:
2 lemons
425 ml water
60 ml white vinegar
135 g coarse salt


Directions:
Cut lemons into cubes, remove seeds and place them in a saucepan with 125 ml of water.
Bring to the boil and simmer for 15-20 minutes, stirring frequently until the water turns like a syrup and the lemons are very soft.
Take off the heat and pour the contents of the saucepan into a blender.
Add the remaining water and blend to a smooth mixture.
Pour through a sieve to remove the pulp; pour back into the saucepan.
Add the salt and vinegar. Mix.
Bring to boiling again and simmer for 10-15 minutes, stirring frequently until it's like a sauce.
Turn off the heat and allow to cool; stirring now and then.
Store in the refrigerator.
