Your Recipe of the Day: Oyster Mashed Potatoes. I haven’t tried this side dish yet, but look forward to it. Chopped, freshly shucked oysters get folded into mashed potatoes with a lemon, curry vinaigrette. The recipe from Aussie site, Eat Well 101, calls for Charlotte potatoes. Since we rarely see Charlottes here in the States, substitute four small Yukon golds.
