White pepper

The mild heat and earthiness of white pepper help to make mashed potatoes a great partner for most proteins and other vegetables.

Kosher salt

While it may seem that any salt will work with mashed potatoes, kosher salt can actually provide certain benefits. The main benefit is precision.

While the status of Parmesan cheese as a spice may be very debatable (it’s not), there is no question that it offers a strong flavor boost to mashed potatoes. Parmesan cheese offers richness and sharpness that stand out in a complementary way against the relatively blank profile of the potato. In addition, it is a great source of glutamates that provide the meaty umami note.
