Types of Sweet Potatoes

Just like many other plants, sweet potatoes have several varieties. Sweet potatoes generally come in two types: dry-fleshed and moist-fleshed.

The dry-fleshed variety has a tan skin and light flesh, almost a tan or yellow color. The flesh is similar to a traditional baked potato and separates into ‘shards’ or sections after baking.

Moist-fleshed sweet potatoes have a darker red skin and a deep rich orange inside. It is these types of sweet potato which are most commonly found in the supermarket and which make the best dish. These sweet potatoes are a dessert in a shell, waiting to be baked and devoured as-is!

1. Yams vs Sweet Potatoes

Yes, yams and sweet potatoes are different! It is common to mix them up and this is mainly the result of different names in different regions.

Sweet potatoes are much sweeter than yams, which are more dry, starchy and neutral flavored, like white potatoes. While both are equally nutritious, the term “yam” refers to a root that is native to Africa or Asia. Their outer skin is dark, bark-like, whilst their flesh is either white or purple in color. Interestingly, most sweet potatoes in the USA are grown in North Carolina. While true sweet potatoes grow in lots of different shades, they are easily recognisable by their tapered ends.

2. Canned Sweet Potatoes

Canned sweet potatoes will work just fine for this recipe and can save you time. Always choose canned varieties with no additives and no added sugar or syrup. Sweet potatoes are sweet enough on their own, and additives can burn and ruin the natural flavors of this dish.

6. White Sugar vs Brown Sugar

Just like yams and sweet potatoes, there is a real difference between white and brown sugar. Baked goods with brown sugar have a more caramel texture and a darker color. White sugar adds sweetness with no change to texture or color.

Measuring white sugar and brown sugar is a very different process. To measure white sugar, just pour it in the measuring cup. Because of its stickiness, brown sugar must be packed into the measuring cup, compact and with no air bubbles.

Brown sugar’s stickiness is due to the high molasses content; white sugar contains no molasses. It is the molasses which makes biscuits, brownies and cookies sweetened with brown sugar a chewier, softer texture.

So, if you want your dessert to be a sweet gift from heaven, use brown sugar! Not only is it a sweetener, it makes chewier baked goods more satisfying.
