What is the main difference between candy yams and yams?
The main difference between candy yams and yams lies in their origin, appearance, and taste. Candy yams are actually a type of sweet potato, belonging to the morning glory family, while true yams are starchy vegetables belonging to the Dioscoreaceae family. Candy yams are native to the Americas, whereas true yams are native to Africa and Asia. In terms of appearance, candy yams have a smooth, thin skin that is often orange or yellow in color, while true yams have a rough, scaly skin that is typically brown or black.
The taste and texture of candy yams and yams also differ significantly. Candy yams are sweet and moist, with a soft, velvety texture, while true yams are starchy and dry, with a firm, waxy texture. In the United States, the term “yam” is often used to refer to sweet potatoes, particularly the orange-fleshed variety, which are commonly used in sweet dishes like casseroles and pies. However, in other parts of the world, true yams are a staple food, boiled, fried, or roasted and served as a side dish or used in sauces and stews.
Where do true yams come from?
True yams are native to Africa and Asia, where they have been cultivated for thousands of years. In West Africa, yams are a staple food, particularly in countries like Nigeria, Ghana, and Senegal. In Asia, yams are widely cultivated in countries like China, Japan, and the Philippines. True yams are typically grown in tropical and subtropical regions, where the climate is warm and humid. They are often planted in well-drained soil and require a long growing season, typically ranging from 6 to 12 months.
In recent years, the cultivation of true yams has expanded to other parts of the world, including the Caribbean and the Pacific Islands. However, the majority of yam production still comes from Africa and Asia, where they are an integral part of the local cuisine and culture. True yams are highly nutritious, rich in fiber, vitamins, and minerals, and are an excellent source of energy. They are also versatile, and can be boiled, fried, roasted, or dried and ground into flour, making them a valuable crop for food security and sustainable agriculture.
Are candy yams and yams interchangeable in recipes?
No, candy yams and yams are not interchangeable in recipes, due to their significant differences in taste, texture, and composition. Candy yams are sweet and moist, while true yams are starchy and dry, which affects the overall flavor and texture of the dish. Using a true yam in a recipe that calls for candy yams may result in a dish that is too starchy or dry, while using a candy yam in a recipe that calls for true yams may result in a dish that is too sweet or soft.
In general, it’s best to use the specific type of yam or sweet potato called for in a recipe to ensure the best results. However, if a substitution is necessary, it’s essential to adjust the recipe accordingly, taking into account the differences in sweetness, moisture, and texture. For example, if using a true yam in a sweet dish, additional sweeteners or spices may be needed to balance the flavor, while if using a candy yam in a savory dish, additional starch or thickening agents may be needed to balance the texture.
Can you grow yams at home?
Yes, you can grow yams at home, but it requires a warm and humid climate, as well as a long growing season. True yams are typically grown in tropical and subtropical regions, where the temperature ranges from 64°F to 90°F (18°C to 32°C). They also require well-drained soil and full sun to partial shade. In temperate climates, yams can be grown in containers or indoor gardens, provided they receive sufficient light and warmth.
To grow yams at home, you’ll need to obtain yam tubers or seedlings from a nursery or online supplier. Plant the tubers or seedlings in well-drained soil, and provide them with regular watering and fertilization. Yams are susceptible to pests and diseases, such as nematodes and fungal infections, so it’s essential to monitor the plants regularly and take action promptly if you notice any problems. With proper care and attention, you can harvest your homegrown yams in about 6 to 12 months, depending on the variety and growing conditions.
How do you store yams and candy yams?
Yams and candy yams can be stored in a cool, dry place, away from direct sunlight and moisture. True yams are typically more delicate than candy yams and require more careful handling. They should be stored in a well-ventilated area, away from other fruits and vegetables, to prevent moisture buildup and spoilage. Candy yams, on the other hand, can be stored at room temperature for up to a week, or in the refrigerator for up to 2 weeks.
To store yams and candy yams for a longer period, you can cure them in a warm, dry place for several days, then store them in a cool, dark place. This can help to dry out the skin and prevent moisture from entering the tuber, which can cause spoilage. You can also store yams and candy yams in the freezer, either whole, sliced, or cooked and mashed. Frozen yams and candy yams can be stored for up to 6 months, and can be thawed and used in a variety of recipes.
Are yams and candy yams nutritious?
Yes, yams and candy yams are both nutritious, but they have different nutritional profiles. True yams are rich in fiber, vitamins, and minerals, including potassium, magnesium, and iron. They are also low in calories and have a low glycemic index, making them a good choice for people with diabetes or those who are trying to manage their blood sugar levels. Candy yams, on the other hand, are higher in calories and sugar than true yams, but they are also rich in vitamins A and C, as well as fiber and minerals like potassium and iron.
Both yams and candy yams are good sources of antioxidants and phytochemicals, which can help to protect against chronic diseases like heart disease, cancer, and cognitive decline.

Overall, both yams and candy yams can be a nutritious and delicious addition to a balanced diet, provided they are prepared and cooked in a healthy way, such as boiling, roasting, or grilling, rather than frying or adding excessive sugar or salt.
Can you cook yams and candy yams in the same way?
No, yams and candy yams cannot be cooked in the same way, due to their significant differences in texture and composition. True yams are typically boiled, fried, or roasted, while candy yams are often baked, mashed, or candied. Candy yams are also more versatile and can be used in a variety of sweet and savory dishes, from casseroles and pies to soups and stews. True yams, on the other hand, are often used in more traditional dishes, such as boiled or fried yams, yam fufu, or yam porridge.
In terms of cooking methods, true yams require longer cooking times than candy yams, due to their starchier and drier texture. Boiling or steaming true yams can help to break down the starches and make them more palatable, while roasting or frying can help to caramelize the natural sugars and enhance the flavor. Candy yams, on the other hand, can be cooked quickly and easily, either in the oven or on the stovetop, and can be mashed or pureed to create a smooth and creamy texture.
