Answering Common Questions about Leek and Potato Soup
While this soup is very easy to make, there are many people who end up with a very salty, runny and even bitter soup. Let’s see how to avoid that.
Why does my leek and potato soup taste bitter?
A bitter taste in your leek and potato soup could come from a few possible sources. One common cause is overcooked or burnt leeks. Leeks, like onions, can become bitter if they’re cooked for too long or at too high a heat. Make sure to sauté leeks over medium heat until they are soft and translucent, not browned. Another reason could be using the green parts of the leek, which are more fibrous and have a stronger flavor. Stick to the white and light green parts for a milder taste.
What starch is used to thicken leek and potato soup?
Traditionally, the starch from the potatoes themselves is used to thicken leek and potato soup. As the potatoes cook and break down, they release starch into the soup, giving it a naturally creamy and thick texture. However, if you prefer your soup even thicker, you can use cornstarch.
Usually, the reason why your soup is too runny is because you’ve used to much stock. Stick to the quantities below and you’ll be fine.
