Add the chopped onion, wild garlic and celery to a large saucepan with a little butter or oil and sweat over a medium heat for 5 minutes.
Add the rice and stir before adding the vegetable stock, chopped lovage, lemon zest, lemon juice and salt and pepper to season. Cover the pan, lower the heat and simmer for 25 to 30 minutes, or until rice is cooked and vegetables are soft.
Check the seasoning before serving with crusty bread and/or croutons.
