Normal Sudoku rules apply.

There are nine "hot potatoes" in the grid -- one each of the digits 1-9, and one in each row, column, and box.

Each hot potato has a buddy in the same row, as indicated by the hot potato's digit. For example, if a hot potato's digit is 1, its buddy is the first cell of that row.

Digits cannot repeat inside a cage. The small clue in the top left of a cage indicates the sum of the contained digits BUT replacing a hot potato's digit with its buddy's.

Thanks to Cristopher Moore for testing!
