Coarsely grate the onions, carrots, celery and garlic – or chop them, if you prefer, but in fairly small pieces.
Heat the oil in a large pan over a medium heat and tip in the vegetables, garlic, herbs and peppercorns.
Sauté, stirring from time to time, for about 5 minutes or until the veg have softened slightly (you’re largely doing this to mellow the raw onion).
Add the wine, if you are using it, then 1.75 litres boiling water from the kettle. Bring back to the boil and simmer, uncovered. If all your veg were grated, the stock will be ready in about 10 minutes. If they were in larger chunks, give it 20–30 minutes. Either way, strain the stock and use straight away, or cool, then refrigerate or freeze.
