Notes

a) Seasoning - Bring out the best in this simple mashed potato by seasoning, seasoning more, then seasoning again. I'll usually go for salted butter for this reason, but feel free to sub unsalted butter if that's all you have.
b) Wholegrain Mustard -  I do strongly recommend using the two different mustards as they both bring s little something different to the table. The wholegrain adds a nice texture to the mash, whilst the dijon adds that classic mustard flavour.
c) Make Ahead - Feel free to make this ahead of time! Just leave off the final drizzle of butter and cover in the fridge. I usually bring to room temp before I microwave so it warms through more evenly. You can also add a splash of cream/milk and stir over medium heat in a suitably sized pot.
d) Calories - based on using 1/2 cup heavy cream and unsalted butter. Divided by 5.
