Larousse De La Cuisine (American Edition) has the following recipe for vichyssoise:
- 250g leeks
- 250g potatos
- 50g butter
- 1.75L water
- 200mL crème fraîche
I was cooking 3 times as much soup, so I multiplied the amount of leeks, potatos, and butter by 3. However, 5.25L was just way too much. I ended up eyeballing it and using ~3L. Still, the end result was a bit too watery for me.
It seems that even the above recipe has too much water. Is this a typo?
Or was it in the scaling up? I can imagine that you do not simply multiply by 3, even if you use a bigger pot than you'd use for the non-scaled version.
