My mashed potato's have become semi-famous in our family circles - near equal parts dairy to potato... lol. My kids brag about them and diss any potato's that don't measure up.
I use real butter, heavy cream, roasted garlic, salt, and fresh cracked pepper. They are rich and full of flavor, almost a food group unto themselves.
So my mother-in-law likes my mashed potato's and said she would like to be able to make them like that for holidays at her place, so I took the time to show her how I made them. Fast forward to the next family holiday, she has informed us she's making "the" mashed potato's. We all tuck in and my kids eagerly await the potato's.... from across the table I could tell something was not right just from looking at them. My kids get them first.... they pile their plates high, they take a big bite... and spit them onto the plate. Both my girls look up with an expression like a puppy that just got smacked on the nose..... and my oldest (13 with no brain to mouth filter) loudly exclaims! "Grandma these potato's suck!"
After much nervous glances and uncomfortable silence the potato's make it to me.... I spoon a small pile onto my plate and take a small taste. They were potato's.... that's all. Just mashed with a little bit of the water they cooked in - no butter, no dairy, no salt NOTHING! It was like eating warm paste (like you used to use in elementary school).
When we got home we discussed the proper technique for expressing a dislike for somebody's cooking.... and did agree that the potato's sucked.
