This puzzle was originally set in January 2022 for the Cracking the Cryptic Discord's monthly prompt of "Haute Cuisine."

• Normal sudoku rules apply.
• A brown line (bacon) must be read the same way from either end (standard palindrome rules).
• Digits along a green line (lettuce) must differ by at least 5 from any neighbor on the line (standard German whisper rules).
• Digits along a red line (tomato) must form a consecutive sequence of non-repeating numbers in any order (standard renban rules).
• A clue outside the grid represents the sum of all bacon, lettuce, and tomato cells between the 1 and 9 (sandwich crusts) in that row or column. Any cells within the sandwich that are not bacon, lettuce, or tomato do not count towards the sandwich sum. The crusts of the sandwiches may not be on bacon, lettuce, or tomato cells.
• Finally, one digit from 2-8 is the secret ingredient and must appear between the crusts of all clued sandwiches in a cell that is not bacon, lettuce, or tomato, and the secret ingredient does not contribute to the sandwich total. The secret ingredient is the same digit in every sandwich and must be determined by the solver.
• In rows and columns without sandwich clues, 1, 9, and the secret ingredient digit may appear on bacon, lettuce, and tomato cells.

Feel free to solve the following example puzzle to understand the rules better. Note that 5x5 sudoku rules apply to this puzzle. The difference between digits on a German Whisper must be greater than 3, The sandwich crusts are 1 and 5, and the secret ingredient must be from 2-4. Solve in CTC or f-puzzles
