Tuber is more peculiar, cut the wrong way (4)

I haven't cracked this one yet — but the brilliant team at Times for the Times have:

ODDE{r} (more peculiar) [cut] reversed [the wrong way]. AKA ‘taro’ apparently, or more interestingly ‘elephant’s ear’. In keeping with  tradition, whenever EDDO appears I assert that I never heard of it before. The TfTT archive confirms I said this in December 2021 and re a puzzle I blogged myself in 2009.
