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.

If you blend or puree the potatoes for too long, the starch inside the potatoes will leak into the broth and create a gelatin-like consistency. It's for this reason, we like to blend the soup in batches (so if we over-blend a little it won't ruin the whole thing!) and only until it's just smooth.

Combine cornstarch and a little bit of water—or the chicken stock from the soup—in a small bowl. With the soup simmering over medium-low heat, whisk in the slurry. The soup should start to thicken almost immediately. Incorporate potatoes.

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.

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 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.

It's really not a good idea to leave it out at room temperature. I've left stock on the stove overnight at a simmer with the lid on. This keeps it hot enough that microbes won't grow but traps evaporation so it can't go dry. It is ok to put the soup in the refrigerator in a fresh room temperature container, covered.

Bring a pot of water to a boil, add the potatoes, and cook for 5-10 minutes until partially tender. Drain and then add them to your simmering soup for finishing. 3. Roasting: For a richer flavor and slightly crispy texture, try roasting the potatoes before adding them to the soup.

Season leeks with soy, maple, sesame oil, and mirin. Top with sliced garlic and a few knobs of butter around the outside of the pan. Add just enough stock to cover leeks halfway, bring to a boil and pop into over to roast until caramelized and tender when pierced with a knife.

How do you fix gluey potato leek soup? ›

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.

Sautéing leeks before adding them to the soup can enhance their flavor and bring out their sweetness. Heat some oil or butter in a pan, then add the sliced leeks. Cook them over medium heat until they become soft and slightly caramelized. This step adds depth of flavor to your soup.

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.

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.

However, if a potato is very green or tastes bitter (an indication of solanine), it's best to throw it away (7). Peeling a green potato and removing any sprouts can significantly reduce its solanine levels. Cooking can also lower the solanine content.
