Normal sudoku rules apply. Digits cannot repeat along the indicated diagonals.
Within the grid are hidden 18 crust cells. The crusts are divided into two sets of 9 cells each. Each set contains one cell in every row, column, box, and indicated diagonal. Additionally, each set contains every digit from 1 through 9 exactly once.
Clues outside the grid give the sum of the digits sandwiched between the two crusts that appear in that row, column or diagonal.
Have fun, leave a comment if you enjoy the puzzle!
PS: I stream solving sudoku like puzzles three days a week. You can check out the channel, as well as some videos I have made about setting puzzles, at my YouTube channel here.
Solution code: Row 7

Silky smooth with a nice little twist at the end, thanks.

Lovely concept, and whilst it felt like hard work for a relative novice, it’s achievable and massively rewarding!

Very crusty !
That was an elegant way of varying the flavour of the crust.
Savoured it until the last bit(e) !

Super fun puzzle. The logic flowed really smoothly, and the double disjoint set was a fun twist!

Very nice. Sandwich-clues are not my favourite, but very happy that I tried this! I liked that you couldn't do the "standard" what's-outside-the-sandwich-trick :-)

This was super fun, and solved very cleanly.

It does not rely on "beta" version of SudokuPad. I've had similar issues with my links recently.
