Tony, I did more SV potatoes, first batch, cooked potatoes, let them cool and that would get rid of some moisture, then put them thru the food mill, and SVed. They had a little more body but the food mill doesn't break up the potatoe enough. You can feel very tiny lumps on the tongue. Here is what they looked like with a dollop of butter.
The second batch I put in the blender to make it creamy. It was easy to do and next time I'd put the cold cooked potatoes directly in the blender.
And now SVed as usual.
Like you I'm feel that I need to add another flavor on top. I'm not sure if it's because the potato tasted different than we expect or not.
