What are Sweet Potatoes?
Sweet potatoes, also known as yams, are tuberous crops with the scientific name Ipomoea batatas. The plant is a creeper with heart-shaped or lobed leaves. The color of the tuber varies from purple or red to pale yellow or white, depending upon the variety, soil type, climate, and available minerals.
The red variety has drier and harder flesh while the white and yellow types have juicier flesh. The red variety has a characteristic aroma which becomes more prominent on boiling. The more reddish or orange the color of the flesh of yams, the stronger the aroma will be. Perhaps, this is due to the presence of beta-carotene, the concentration of which also increases with the color.
