Sweet potato casserole
Sweet potato casserole is a Southern Thanksgiving side dish from Georgia to Louisiana, and it now sits beside the turkey on tables right across the United States, as well as at Christmas dinner. Roasted sweet potatoes are whipped with butter, a little brown sugar, egg and warm spices, then baked under a crisp pecan streusel. Some families top it with marshmallows instead; if you do, buy vegetarian ones made without gelatine. It contains tree nuts (pecans), milk, egg and wheat. The common mistake is boiling the potatoes, which makes the mash watery and bland; roasting them in their skins concentrates the sweetness and colour. Doneness: the filling should be set and hot right through and the topping golden and crunchy. Chef's tip: roast the potatoes a day ahead and keep them in the fridge; cold, peeled flesh whips smoothly and saves time on the big day.
