Savoursmiths Christmas Ham with Umami Truffle Glaze Flavour Potato Crisps Turkey has gone murkey, and so we decided to steer clear of that. This Christmas is the time for Ham with a decadent Umami Truffle Glaze. Our Vegan Christmas Ham gives an almost bacon type flavour, which has always been hugely popular and tasty on a crisp. Umami is very much in vogue at present, giving a very pleasant savoury taste, and is used to balance taste, and round out the overall flavour of a dish. Umami enhances the palatability of a wide variety of foods and it is a natural enhancer of flavour – making this crisp burst with flavour! The truffle then adds to the flavour by giving a more earthy depth to the taste, and nicely rounds off an overall decadent flavour.
