The sweet potato (La patate douce)

I really appreciate having a nutritious meal with sweet potatoes and fresh vegetables. From mashed to roasted, I love how versatile sweet potatoes are. Unfortunately, it has not always been like this. Although sweet potatoes were part of my mum’s cooking, I never was a big fan when I was living in Guadeloupe Archipelago. As far as I can remember, my mum constantly strove to make my siblings and I enjoying this root vegetable. Let’s find out more about this tuberous root.

Origin & Description

The sweet potato is native to Central and South America and has been grown for over five thousand years. Sweet potatoes are cultivated throughout tropical and warm temperate regions wherever there is sufficient water to support their growth. The sweet potato plant has simple heart-shaped leaves that are pale or dark green-coloured. The flowers are white or lavender. The most important part of the plant are the roots called tubers. The tuber is edible, sweet, rich in starch, fibre, vitamins, and minerals as well as varying in size, shape, taste and texture. Sweet potatoes flesh can be white, yellow, orange, red or purple, while skins’ colours range from yellow, pink, orange, red to brown. When I was living in Guadeloupe Archipelago, I have always seen my mum cooking the white-fleshed and red-skinned variety. Here in the UK, the one with orange flesh and pink skin is quite popular.

Culinary Use

Sweet potatoes tubers can be: Baked, boiled, fried, grilles, juiced, microwaved, pureed, steamed and even toasted. There is a current trend with sweet potato toasts to enjoy with your favourite topping. Apparently, white, or pale yellow-fleshed sweet potatoes are less sweet and moist than those with red, pink or orange flesh. This has made me understand why my mum always cooked sweet potatoes as a savoury dish such as: Boiled sweet potato with fish, sweet potato fries, or sweet potato gratin. On the other hand, sweet potatoes are widely used in sweet dishes such cakes, cookies, pies, pudding, and others delicious desserts. Nowadays, lots of products are made from sweet potato including: flour, bread, cereals, crisps, juices, noodles, and candy. The sweet potatoes leaves can also be eaten as a vegetable, boiled or in salads.
