For the absolute best mashed potatoes, buy russets. Dry them out after boiling (steam them for a minute in the pot). Warm your cream and butter before adding—cold dairy is the enemy. Mash gently, and add salt like you mean it.
But if you want to flex at dinner parties, use Yukon Golds and finish with a splash of warmed buttermilk. The tang cuts through the richness and makes people ask, “Did you use something special?” You can smirk and say, “Just potatoes, darling.”
One last tip: never, ever peel the potatoes if you want a rustic, “I’m a farm-to-table influencer” vibe. But if you want smooth perfection, peel them like your grandmother would—with a sharp peeler and a judgmental look. Your guests will thank you.
Now go forth and mash. May your butter be melty, your lumps nonexistent, and your potato choices eternally wise. And if someone asks for red-skinned mash, just pretend you didn’t hear them.
