What Are Yams?

– White Yam: The most common type, primarily found in Africa.

Sweet potatoes have a smooth skin, ranging from yellow to orange and even purple, depending on the variety. Their flesh is usually sweet, creamy, and rich in nutrients.
These tubers can be divided into two main categories: firm and soft. Firm varieties remain stable during cooking, while soft sweet potatoes become creamy and soft when cooked. Sweet potatoes are incredibly versatile, suitable for both savory and sweet dishes, including pies, soups, and fries.

Choosing the right variety enhances the flavors and textures in your dishes.
