Ingredients
Directions
Skim and heat
Remove all scum from the water and keep it below boiling point until removed.
Bring the water to a boil after removing the scum.
Make the stock

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Adds savoury depth and aroma to the stock as they cook slowly in the water.
- Carrots
- Release natural sugars that add gentle sweetness and roundness to the stock.
- Leeks
- Contribute a mild, sweet onion-like aroma to the stock.
- Turnips
- Add a light, slightly peppery background flavour to the stock.
- Celery
- Adds fresh, herbal aroma that rounds out the stock's flavour.
The step that matters
Keep the stock below boiling after skimming. Hard boiling agitates the liquid and breaks up scum and fat into fine particles, clouding the stock. Gentle simmering lets impurities rise and collect on the surface so they can be removed, keeping the stock clear.
Swap the onion
