Sweet Potato varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common sweet potato varieties compare.

Variety	Best for
Beauregard	Everyday baking, mash, and roasting: deep orange flesh, sweet and reliably moist; the standard US supermarket sweet potato.
Garnet	Mash, pies, and casseroles: red-purple skin and deep orange flesh, very moist and sweet.
Jewel	Roasting and baking whole: copper skin and orange flesh, mild and sweet with a moist texture.
Japanese (Murasaki)	Roasted wedges and savoury sides: purple skin and pale flesh, drier and less sweet with a chestnut flavour.
Stokes Purple	Showpiece purées and colourful plates: purple skin and deep purple flesh, slightly drier and earthy.

Which should I pick?

For everyday baking, mashing, and roasting, Beauregard is the supermarket default: deep orange flesh, sweet and reliably moist. No Beauregard? Garnet or Jewel are interchangeable orange-flesh substitutes, equally sweet. For drier, savoury dishes and roasted wedges, Japanese (purple skin, pale flesh) holds its shape with a chestnut sweetness. Stokes purple-flesh sweet potatoes are the pick for colourful purées and showpiece plates.
