Mary Berry's Potato Leek Soup (2024)

FAQs

Why does my leek and potato soup taste bitter? ›

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.

If your soup tastes anything but super flavorful, you likely just need to add more salt! Toppings like fresh herbs (I like chives and thyme), croutons, bacon, or cheese help, but this soup should be flavorful on its own and salt should be the first thing you add if your soup tastes bland.

Why is my potato leek soup gummy? Potatoes should be diced in similar size so they cook evenly, but don't drive yourself crazy getting them teeny-tiny. If they're too small, you risk the potatoes releasing too much starch, which can make the soup gummy when pureed.

Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry.

It looks as though some of your potatoes might have got a bit scorched. Did you fry them off before adding the liquid? The colour from the browned potatoes could be what is turning it brown.

Sweetness can help balance bitterness, so consider adding ingredients like carrots, onions, or a small amount of sugar or honey. Acidic ingredients like tomatoes or a splash of vinegar can also help balance flavors.

"If your broth is lacking in savory richness, try adding roasted onion, tomato paste, mushrooms, seaweed, soy sauce, or miso. These ingredients add umami flavor and depth to broth," she says. The choice of ingredient depends on the recipe, though.

Add flour or cornflour

Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer. Cook for a few minutes to allow the starch granules to burst to thicken, and to cook out any flour flavour.

For an extra-smooth soup, press it through a chinois or a fine mesh strainer using the bottom of a ladle. Sure, it's the gluier than its pressed brother, but as I said, sometimes that really doesn't bother me.

FYI – with potatoes, you want to blend only as much as necessary to get a smooth texture. Blending them too long can make them gummy. Once all the soup is pureed you can pour it back into the pot and rewarm, or simply scoop and serve!

How do you keep potatoes from getting mushy in potato soup? ›

How do you keep potatoes from getting mushy in soup? Keeping the skins on your potatoes will help. Also key to remember is that when chopping the potatoes, the smaller they are the faster they will cook. So, don't be afraid to cut them a little on the larger side than you normally would.

When you are sauteing onions to build flavor as a base for your dish (soup, tomato sauce, you name it), the yellow onion is your friend. That being said, white onions are a totally acceptable substitute for yellow, especially if you're cooking them.

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

You need to cut or scrap any green parts of the potato flesh or skin and discard those pieces. The other parts of the potato are usable. Because of this, it's important to store potatoes properly. A cool, not cold, dark and dry place is best.

Soaking the onions in cold water for 10 minutes before cooking can help to reduce the unpleasant taste and smell. Additionally, adding a pinch of sugar to the cooking onions can also help to reduce their pungent flavor.

Leeks have a mildly sweet flavor that is reminiscent of other alliums, such as onions, shallots, garlic, and chives. They are often used the way onions are — as part of a base of flavors for soups, stews, and other long-cooking dishes.
