Julienne Soup
Ingredients
Directions
Prepare the vegetables
In a saucepan, combine the shredded carrots, turnips, parsnip, leeks, butter, salt, and sugar.
Cover and cook on low heat for 10 minutes in summer or 15 minutes in winter, shaking the pan occasionally.
Add the shredded lettuce and celery, and cook for another 4-5 minutes.
Simmer the soup
Gradually add the boiling water and pepper, then let the mixture simmer for 1 hour.
If in season, add the green peas, French beans, and asparagus, and simmer for an additional 30 minutes.
Before serving, stir in 1 tablespoon of butter for added richness.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, colour and body as they soften during the long simmer.
- Turnips
- Add mild sweetness and a tender, starchy body to the broth.
- Leeks
- Contribute a gentle onion-like aroma and sweetness to the base.
- Butter
- Adds fat for a rich mouthfeel and helps carry the vegetable flavours.
- Sugar
- Balances the savoury flavour and enhances the caramelised sweetness of the vegetables.
- Lettuce leaves
- Add a delicate, slightly sweet vegetal flavour and soft texture.
The step that matters
Cooking the vegetables gently in butter before adding water. Cooking the vegetables covered on low heat draws out their moisture and sweetness without browning, building flavour into the base. Adding boiling water too early or at high heat can leave the vegetables bland and the broth weak.
Swap the celery
