Streaming the alder for 15 minutes in a vegetable steamer prevented any reddening. I think I'd also get a different color if i used more aged wood. Thanks for the suggestion @encnerwal!

Update: oxalic acid will remove all reddening and vinegar will remove most.  The bowl ends up a bit more of a yellow color overall.
