Zero Waste Vegetable Broth
As you cut down on plastic, refill household cleaning products rather than buy new bottles, and upcycle items rather than discard, extend that zero-waste initiative to your menu planning.
Add this zero-waste vegetable broth to your weekend cooking and you’ll have a base for delicious soups, nutritious sauces and extra portions to freeze for a homemade ready meal.
Christine calls this nourishing vegetable stock ‘Righteous Broth’, because after you make it you feel absolutely righteous for not wasting a scrap!
This is less a ‘recipe’ as it is a ‘technique’:
Throughout the week, save all scraps from vegetable prep – tops and tails of carrots, celery, onions, courgettes. Save peelings from parsnips and potatoes, ragged mushroom stems, tough kale stalks. Set aside cauliflower cores and woody broccoli bases. Keep a container in the fridge or the freezer, adding to it as you prepare each meal.*
On Friday or Saturday evening, pop the contents of the container into a slow cooker, add water to cover, and set the dial on ‘low’ to cook slowly overnight. Alternatively, put the vegetables into a large saucepan, cover with water, and cook on the lowest setting on the hob for at least three hours, making sure the stock is at the barest simmer. We want to leech the nutrients from the vegetables as low and slow as possible.
The next morning (or just before bed if you’re cooking on the hob): strain the stock, toss the scraps in the compost bin, and relish the rich, deep golden hue of your homemade, zero-waste vegetable broth! The scent will be unlike any stock cube you’ve ever bought, and the nutrient value leaves instant soups lagging far behind.
