👨‍🍳 Method

1. 1
   Heat the butter and oil in a pot over medium heat.

   StovePot
2. 2
   Add the onion and fry for 8–10 minutes, stirring, until the onion is soft and deep golden.

   Stove

   💡Add by cooking time: what needs long (onion, carrot, meat) goes in first, and what burns fast (garlic, dry spices) goes in last, only until fragrant.
3. 3
   Add the garlic and fry about 30 seconds to 1 minute, just until fragrant. Don't let the garlic brown.

   Stove

   💡Garlic burns quickly and turns bitter. Add it only after the onion has softened, over medium heat, and add the next ingredient as soon as it smells fragrant.

To assemble

1. 4
   Add the vegetables and fry 7–8 minutes, stirring, until it is golden.

   Stove

   💡Whatever is fried before the liquids browns at the edges, and its flavor concentrates.
2. 5
   Sprinkle in the gluten-free flour blend and stir for a minute.

   Stove
3. 6
   Put the onion, carrot, celery, parsley, garlic, bay leaves and thyme in a large pot with the cold water.

   💡Start with cold water: the vegetables release their flavor slowly as the water heats up.
4. 7
   Bring to a boil over high heat and skim off the foam.

   Stove
5. 8
   Turn down to medium-low heat and simmer uncovered 30–45 minutes.

   Stove

   💡A gentle simmer, not a boil: a hard boil dries the food out and clouds it, a slow simmer cooks it evenly.
6. 9
   Strain the stock through a fine sieve.

7. 10

   Stove
8. 11

   Stove
9. 12

10. 13
    Add the cream, season with salt and black pepper and heat another 5 minutes.

    Stove

    💡The cream or cheese goes in after blending, over low heat: a hard boil after adding them can make the soup separate.
11. 14
    Serve with the parsley.
