Method
Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper.
Pierce the sweet potatoes all over with a fork to allow steam to escape. Place them on the prepared baking sheet and roast until completely soft and tender, yielding easily to a squeeze.
While the potatoes are roasting, use a microplane to zest the lemon. Combine the butter, heavy cream, bourbon, lemon zest, nutmeg, cloves, black pepper, and salt in a small saucepan.
Heat the saucepan over low heat until the butter is completely melted and the mixture is warm and fragrant. Keep warm until the potatoes are ready.
Remove the sweet potatoes from the oven and let them cool for a few minutes until safe to handle. Peel away the skins and discard them, transferring the warm flesh to a food processor.
Pour the warm butter and cream mixture over the sweet potato flesh. Puree until completely smooth, scraping down the sides of the bowl as needed to ensure an even, silky texture.
Taste for seasoning, adjusting salt if necessary. Transfer to a serving dish and serve immediately.
Chef's Notes
- Roasting the sweet potatoes whole instead of boiling them is crucial. Boiling waterlogs the flesh and dilutes the flavor, while roasting concentrates the natural sugars and creates a superior, velvety consistency.
- If substituting orange juice for bourbon, add it off the heat right before pureeing. Boiling fresh orange juice can dull its brightness and introduce a slightly bitter note.
- Do not skip warming the dairy mixture before adding it to the potatoes. Adding cold cream and butter lowers the temperature of the dish and prevents the fats from emulsifying smoothly into the starch.
Storage
Refrigerator: 5 days — Store in an airtight container. The flavors will deepen overnight.
Freezer: 3 months — Freeze in a freezer-safe bag or airtight container. Thaw overnight in the refrigerator before reheating.
Reheating: Reheat gently on the stovetop over low heat, adding a splash of cream or milk to restore the silky texture.
