Ingredients
1 onion
1 carrot
1 leek
2 celery sticks
Any other left-over vegetables in the fridge, eg. cabbage stalks, Brussels sprout heads.
Salt Herbs/spices eg. 3 bay leaves, 4-6 juniper berries, whole peppercorns.

Method
Wash and chop vegetables roughly. The vegetables can be old and tired, and you can leave out anything you don’t have.

Fill the slow cooker with chopped vegetables until it’s two-thirds full, season with salt, add the whole spices if using and tuck the bay leaves down the sides. Fill the pot with boiling water until it covers the vegetables. Cook on auto, or on high for 1 hour and low for a further 5-7 hours.

Strain the liquid through a sieve, pressing on the vegetables to extract all the liquid.
The stock can be frozen once cold and defrosted before use. A suggestion is to freeze the stock in lidless glass jars – the lids can be put on after the liquid is frozen.

You can add chicken bones to this stock if you have them!
