Place the cubed sweet potatoes in a large pot and cover with water. Add a big pinch of salt.
Bring to a boil and cook for 20–25 minutes or until the sweet potatoes are very tender.
Drain the potatoes:
Pour the potatoes into a colander to drain, and return the pot to the stove.
Return the potatoes to the warm pot and allow them to dry off using the residual heat from the stove.
Blend into a purée:
Transfer the potatoes to a food processor with butter, milk, sour cream, Aleppo pepper, and paprika. Blend until smooth, adding more milk if a creamier consistency is wanted. Taste and add more salt and pepper.
To serve:
Spoon the purée onto a serving platter and garnish with more Aleppo pepper or paprika. Enjoy!
Notes
You can use a food processor, immersion blender, hand mixer, or potato masher depending on what is available to you. A food processor or immersion blender will help you achieve the silkiest texture.
