People often wonder, “Are yams sweet?” It’s a common question because the word “yam” can be a bit tricky. Sometimes, what we call yams in the store are actually sweet potatoes! This can make figuring out their taste a little confusing for folks who are new to cooking with them.
Don’t worry, though. We’re going to make it super simple to know for sure. Let’s clear this up so you can enjoy delicious dishes.
We’ll break down what makes them sweet and how to tell the difference.
Understanding Yams And Their Sweetness
What Exactly Is A Yam?
When most people in North America say “yam,” they are usually referring to a type of sweet potato. True yams, on the other hand, are a different group of starchy root vegetables that are native to Africa and Asia. They have a rough, bark-like skin and can be quite large.
Their flesh can range from white to purple to reddish-brown. True yams are generally less sweet and more starchy, similar to a regular potato but with a distinct earthy flavor.
The confusion often comes from how these terms are used in different parts of the world and in grocery stores. In the United States, the term “yam” has been widely used for certain varieties of orange-fleshed sweet potatoes. These sweet potatoes were given the name “yams” by enslaved Africans in the American South because they resembled the yams they knew from their homeland.
Over time, this usage stuck, leading to the common mix-up.
Are The “Yams” You Buy Sweet?
This is where the main confusion lies. The sweet potatoes that are commonly sold as “yams” in the United States are indeed sweet. These are typically the varieties with moist flesh and deep orange or reddish skin.
When cooked, their natural sugars caramelize, making them taste very sweet. Think of mashed sweet potatoes or sweet potato pie – those delicious flavors come from these sweet varieties.
So, if you are in the US and picking up what the label says is a “yam,” chances are very high that it is a sweet potato, and yes, it will be sweet when cooked. The sweetness can vary a bit depending on the specific variety and how it’s prepared, but generally, these are sweet and tasty.
The True Yam’s Flavor Profile
If you happen to find a true yam, its taste is different. True yams are typically drier and starchier. They don’t have the same intense sweetness as their sweet potato cousins.
Their flavor is more subtle and earthy. When cooked, they have a texture closer to a regular potato, though some varieties can be a bit fibrous. They are often used in savory dishes, stews, or roasted as a side, much like you would use a white potato.
Because true yams are less common in many Western supermarkets, most home cooks in places like the US are not familiar with their unique taste. When the question “Are yams sweet?” is asked by someone in these regions, they are almost always thinking about the sweet potato variety. This distinction is key to understanding the differing answers you might get.
Sweet Potato Varieties Commonly Mistaken For Yams
Several types of sweet potatoes are often labeled as yams. The most common ones have moist flesh and a reddish-brown or copper-colored skin. These are known for their high sugar content, which makes them very sweet after cooking.
Some popular varieties include:
- Beauregard Sweet Potato This is one of the most common varieties and has bright orange flesh. It’s known for its sweetness and moist texture.
- Jewel Sweet Potato Another popular choice with vibrant orange flesh and a consistently sweet flavor.
- Garnet Sweet Potato This one has deep reddish-orange flesh and a rich, sweet taste, often considered one of the sweetest.
These varieties are excellent for baking, roasting, or mashing, and their natural sweetness shines through in many recipes. They are the source of the “sweet” reputation many associate with yams.
The Starchy Difference True Yams Make
True yams, on the other hand, are quite different in texture and flavor. They are generally drier and have a less pronounced sweetness. Their starchiness means they hold their shape well when cooked, making them suitable for dishes where a firmer texture is desired.
Here are some characteristics of true yams:
- Rough, dark skin that can be woody or fibrous.
- Drier, starchier flesh, which can be white, yellow, or purple.
- More earthy and less sugary flavor compared to sweet potatoes.
- Texture is often compared to a regular potato, but with a unique bite.
If you are looking for true yams, you might find them in specialty ethnic food stores or international markets. Their culinary uses are different, focusing on their starchy quality rather than their sweetness.
How Cooking Affects Sweetness
The way you cook these root vegetables can also bring out their sweetness. Both sweet potatoes (often called yams) and true yams change when heated.
When sweet potatoes are cooked, their complex carbohydrates break down into simpler sugars. This process is called caramelization, and it makes them taste much sweeter. Roasting and baking are great methods for enhancing this natural sweetness.
Boiling can also work, but it might result in a slightly less intense sweetness compared to dry heat methods.
True yams, being starchier, also undergo changes. While they don’t have the same level of natural sugars to caramelize into intense sweetness, cooking them makes their starches more digestible and softens their texture. Their earthy flavor remains, but cooking makes them more palatable.
Identifying Yams vs. Sweet Potatoes
The easiest way to know if you’re getting a sweet root is to check the label at the grocery store. If it says “sweet potato,” you’re likely getting a sweet one. If it says “yam,” especially in the US, it is probably a sweet potato variety.
If there is no label, you can often tell by appearance.
- Sweet Potatoes (often called yams): Typically have smoother skin, ranging from copper to reddish-brown to purple, and their flesh is usually orange or yellow. They tend to be more elongated and tapered at the ends.
- True Yams: Usually have rough, bark-like skin that is very dark brown or black. They are often cylindrical or irregular in shape and can be much larger than sweet potatoes. Their flesh color varies more widely, from white to yellow to purple.
When in doubt, the texture and skin are good clues. If it feels smooth and looks like it might be moist inside, it’s probably a sweet potato. If it looks rough and dry, it might be a true yam.
Culinary Uses: Sweet Or Savory?
Sweet Applications For “Yams” (Sweet Potatoes)
The sweetness of sweet potatoes makes them a star in many desserts and sweet side dishes. Their natural sugars are perfect for baking and create delightful flavors.
Popular sweet dishes include:
- Sweet potato pie
- Sweet potato casserole with marshmallows
- Sweet potato bread or muffins
- Candied yams (a classic holiday dish)
- Sweet potato fries (a popular alternative to regular fries)
These dishes often highlight the natural sweetness and moist texture of sweet potatoes, making them a beloved ingredient for celebrations and everyday meals alike. The ability to caramelize means they pair wonderfully with spices like cinnamon, nutmeg, and ginger.
Savory Dishes With True Yams
True yams, with their starchier texture and earthier flavor, lend themselves well to savory preparations. They can often be used in place of regular potatoes in many recipes.
Some savory ideas for true yams:
- Boiled or steamed as a staple starch in many African cuisines.
- Roasted with herbs and spices for a hearty side dish.
- Added to stews and curries for thickness and substance.
- Mashed with butter and salt for a simple, starchy side.
- Fried into chips, similar to potato chips, offering a less sweet alternative.
Their ability to hold their shape and their more neutral flavor profile make them versatile for dishes where you don’t want excessive sweetness.
