Storage: This pudding can be stored wrapped in foil and plastic wrap in the refrigerator for up to a week or frozen for longer storage. Reheat by steaming for 30 minutes before serving.
Substitutions: If you cannot find suet, you can use finely chopped unsalted butter or a neutral vegetable shortening, though the traditional texture may vary slightly.
Tip: Ensure the water in the steaming pan never boils over into the pudding mold. Keep the heat at a steady simmer.
Variation: For a boozy twist, add 2 tablespoons of dark rum or brandy to the batter along with the vanilla.
