Instructions: Add 55g of butter and 3 handfuls of grated parmesan cheese to the mash (qv).

Mix this in well and add 1 tablespoon of truffle oil (you can add this to taste).

Truffle oil is now widely sold in supermarkets.

Its probably not the real McCoy because the stuff I saw last week was quite cheap but it is quite an interesting taste anyway and is probably worth trying.
