The Rules:
- Normal Sudoku rules apply.
- Battenburg: the four cells surrounding a small Battenburg cake slice must contain 2 odd and 2 even digits - the even digits and odd digits around the small square must not be orthogonally adjacent to each other.

I was a little doubtful at first glance that it would anything more than just basic sudoku, but the colouring was very fun! lovely stuff :D

Very tasty.
For avoidance of doubt for other solvers, batterburg sometimes has a negative constraint (all battenburgs are given). That is not the case in this puzzle, 2 odds and 2 evens can appear in a checkerboard pattern without a battenburg being present.
Yes - that was a common feature of Battenburg puzzles - but I feel that negative constraints work better in more tricky puzzles.

Took me a few minutes to grok that this was a colouring puzzle. Liked the back and forth between colouring and sudoku. So many colouring puzzles are do all the colours first, then solve for the cells.
