Ingredients
- Russet potatoes
- Yukon gold potatoes
- 1 teaspoon salt
- 3 tablespoons cold butter
- 1/2 cup sour cream
- 1/4 cup reserved potato water
- Salt and pepper to taste
- 1 teaspoon extra melted butter
- Green onions
Step 1: Prepare and Cook the Potatoes
Peel and roughly chop russet potatoes into uniform pieces to ensure they cook evenly.
Place the chopped potatoes into a pot of boiling salted water (about 1 teaspoon of salt).
Bring the water back to a simmer after adding the potatoes and let them cook for about 20 minutes, or until fork tender.
Step 2: Drain and Season the Potatoes
Test the potatoes with a fork; they should break apart easily.
Drain the potatoes, reserving a little bit of the potato water for later use.
Add about 3 tablespoons of cold butter to the drained potatoes and mix to help it melt with the heat of the potatoes.
Season the mixture with salt and pepper to taste.
Step 3: Add Sour Cream and Reserved Water
Add one heaping half cup of sour cream to the potatoes.
Gradually mix in about a quarter cup of the reserved hot potato water until you reach your desired consistency.
The reserved water helps to make the mash smooth and creamy without being too dense.
Step 4: Mash and Serve
Mash the potatoes to your preferred texture, whether smooth or with some lumps.
Plate the mashed potatoes and drizzle with about a teaspoon of extra melted butter for presentation.
Optionally, snip some green onions on top for garnish, or mix in more green onions with the butter for added flavor.
