It took me a long time to figure out how to make good mashed potatoes. Make them healthier by using low-fat buttermilk. Buttermilk is lower in fat than regular milk and it also gives the mashed potatoes extra flavor.
2 large Russet or 3-4 smaller variety of potato like Yukon gold or red
1) Fill medium-large pot ¾ full with water and bring to boil.
Add ½ tbsp. butter and good dash of salt to water.
Feel free to add roasted garlic, sour cream, chives, cheese, or whatever you like. Leave the potato skins on if you like them that way. I don’t like skins in my mashed potatoes.
