Fifteen Kilograms of Imperfect Lemons

This is surprisingly delicious. I had a lot of celery from my food box and wanted to use it up.

Chop up a bunch of celery and a clove of garlic and fry in 30g butter. Add 300ml stock and a bay leaf and a sprig of thyme. Reduce by half then bake in the oven at 180 degrees celcius.
