  3. I still can find when to put the minced garlic in the potatoes. It is in the recipe, but where does it go? I did not use it and the potatoes were still excellent. Took it to a church dinner.

    • Sorry. I put it into the potatoes when I am mixing through the cream cheese etc. It would be in the second step in the recipe card. Thanks.
