Melt 25 g salted butter in a pan then pour in 150 ml whisky
Set whisky alight with either a long lighter or match and wait until all the alcohol cooks off (give the pan a shake to ensure all the alcohol ignites)
Add 1 teaspoon dijon mustard and 1 beef stock cube dissolved in 100 ml water - stir to ensure even distribution
Pour in 200 ml double cream and simmer for 5 minutes on medium/high heat
Finally, season with ⅛ teaspoon salt & ⅛ teaspoon white pepper
Note: if you allow the sauce to ‘sit’ for a few minutes after you’ve turned the heat off it will thicken further as it cools
