Which Beetroot?

I tend to grow lots (because P likes them) then forget to thin them, then the rest of the produce comes in and they get forgotten in favour of beans and courgettes. I've got cylindra, boltardy, choggia, crosby's Egyptian, touchstone gold and golden eye currently languishing in the patch. I too find the yellow ones sweeter but as Scarlet said they can look a bit grey after pressure cooking and I found the yellow ones bolted more than the red. I think I'd better start using some up and doing a taste test.
