Blade Mace. Bit of a weird one this but so tasty. It is the outer casing of the nutmeg which has a more subtle flavour than the nutmeg - which can be quite full on at times. Use a spice grinder to reduce to a powder just before adding to preserves that need that unmistakable 'Christmassy' flavour. Try infusing the whole husk in milk to make sauces like bechemel or bread sauce
