Making mashed potatoes a little more mysterious by adding a few ingredients won’t necessarily complicate your life. It will just add some spice to the taste.
A basic recipe I’ve duplicated from my mom is her sour cream and garlic mashed potatoes. Cube the potatoes, boil for 20 minutes (keep the skins on if you like them), drain, then dump them in a bowl with butter, sour cream, garlic, and pepper. Season it the way you like.
For three potatoes, which will easily feed six people, dump in your personal appropriate amount of each added ingredient. For us, that would be about 8 ounces of sour cream, half a stick of butter, a large tablespoon of garlic (I keep a large jar of chopped garlic handy) and 3-4 good shakes of pepper.
If you run out of sour cream, use cheese. You can never get enough cheese.
Then, just mash all the ingredients together in a large bowl until they reach the consistency you desire.
It’s delicious and is ready in 20 minutes once you have the water boiling.
