What each ingredient does
- Broth
- Forms the main liquid base and carries most of the savoury flavour of the soup.
- Onion
- Softens as it cooks, adding sweetness and aroma to the broth.
- Oatmeal
- Its starch thickens the broth as it cooks, giving the soup body.
The step that matters
Stirring while the oatmeal cooks. Oatmeal starch thickens the liquid but can settle and scorch on the bottom of the pot. Stirring often keeps it evenly dispersed and prevents a burnt taste.
