Sweet Potatoes Roll/ 고구마빵/蕃薯卷

Sweet Potatoes are large,starchy, sweet-tasting. Besides simple starches, sweet potatoes are rich in complex carbohydrates, dietary fiber, beta carotene ( a vitamin A equivalent nutrient), vitamin C and vitamin B6.

The flesh range from beige through white, red, pink, violet, yellow, orange and purple. Sweet potatoes varieties with white or pale yellow flesh are less sweet and moist than those with red, pink or orange flesh.

Pink, yellow and green varieties are high in carotene, the precursor of vitamin A. Sweet potatoes varieties with dark orange flesh have more carotene than those with light-colour flesh.

In certain parts of the world, sweet potatoes are locally known as camote, kamote, goguma, man thet, ubi jalar, ubi keladi, shakarkand, satsuma imo, batata or el boniato.[5] In New Zealand English, the Māori term kūmara is commonly used.
