You're out of pickles but in a desperately need some. This is a recipe you can use.
Combine vinegar, water, sugar and salt in a pot and bring to the boil.
After the sugar and salt dissolves, transfer the mixture to a bowl and let it cool.
Clean the carrots and cut into very thin julienne strips using a mandoline slicer.
Put the carrots in a glass jar. Add coriander seeds and crumble the bay leaves over the top.
Fill the jar with the water-vinegar mix you made earlier. Make sure that it covers everything.
Cap the jars and leave them for 2 hours.
