Why does my leek and potato soup taste bitter? ›

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.

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.

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.

So what do you do if you've made the mistake of using starchy potatoes in your soup? One trick to make your potato soup a little less grainy is to add some form of dairy –- cream, milk, or even cheese. Because dairy is generally creamy in texture, that characteristic will carry over into your soup.

Add sweet vegetables like carrots and beets. They will sweeten the broth and deepen its color. You might also add a bit of miso (or salt) and/or a squeeze of lemon juice. Sweet, salt and acid balance bitter flavors.

What do I do if my soup is bland? If your soup tastes anything but super flavorful, you likely just need to add more salt!

If not, some mild acidity will help, adding a squeeze of lemon juice may do it for you. Bitterness is best counteracted by salt, so give it a good seasoning. You might also try adding a little mild vinegar like white wine or cider vinegar.

It turns out, then, that contrary to internet opinion, it is possible to redeem your potato leek soup if somehow it becomes gluey. Ladle some into a freezer bag, freeze it flat, thaw it, and pour off the water.

Cornstarch is a great option as it is a natural thickening agent, but you'll want to be careful about how much you use. Start with 1 tablespoon of cornstarch whisked together with cold water to create a slurry. Then, gradually add the slurry to the soup, letting it boil for one to two minutes before adding more.

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.

Will cream cheese thicken potato soup? ›

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.

Cream, crème frâiche and sour cream add a luxuriously rich flavour and silky texture to soups, but you need to wait until the soup has cooled a little first, or they will curdle. Remove the soup from the heat and wait for a minute or two after it stops boiling, then stir in the creamy thickener of your choice.

If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

Method 1: Whisk in a slurry of cornstarch or flour

Add equal parts water or soup liquid to the flour or cornstarch and whisk until they're completely combined in a slurry. Once you've created the slurry, slowly whisk it into soup liquid and bring it back to a simmer.

To serve it up, sprinkle on a little extra parsley before adding some of the grated cheese… And—you'd better believe it—some of the crispy bacon. You can also add sliced green onions, a dollop of sour cream—anything you want! This soup will warm your ever-loving heart and soul.

Most recipes use the leek's white and light green stems, which is where that mild onion-like taste lives. That's no shade to the dark green leaves because those are edible, too—they just tend to be more bitter.

According to this article from Caroline Wright, a lecturer in horticulture, "there can still be a bitter flavour to potatoes that have begun to grow." Exposure to light produces solanine. Solanine is a bitter toxin and even when pared from the potato, can have imparted bitterness throughout the spud.

Sweetness: From sugar, honey, fruits or otherwise, sweetness will counteract bitter and sour flavours. It can also be used to cut down the heat of a particularly spicy meal. Saltiness: Salt plays two very important roles in flavouring a dish. Firstly, it balances against bitterness.
