    Mine have arrived too - They are stunning Paul, thank you. They put the ones that I managed to grow a couple of years ago to shame. I shall enjoy growing these this year

    Thanks from me as well, Paul. The Oca tubers arrived safely today.

    Do be aware that oca contains very high levels of oxalic acid and just eating them straight from harvest is probably not too good for you and gives them a strong flavour. Some types of oca were originally soaked in water for a considerable period but the 'sweet' oca here just needs to be left out in the sun for a few days to improve the taste and reduce the oxalic acid content. I remember feeling quite sick after eating these when we first grew it and did nothing to the tubers.

    I've grown Oca before and taken them straight from the pot (always grow them in a pot) into the kitchen then steamed them. Never noticed a strong taste before

    It's well documented (the oxalic acid thing) and people say the flavour improves if you expose them. As for reactions, some people can munch happily on Jerusalem artichokes while I dare not touch the things (I've tried many times, cooking them differently each time) as I get far worse than just wind! Even Chinese artichokes (Crosnes) present me with a 'challenge' and they aren't even remotely related. Must admit my reaction to Oca wasn't as bad as either of those two things!

    I know that Oca is meant to have a lemony taste due to the oxalic acid but nope cannot taste any lemon. I wonder if growing conditions can affect the level of oxalic acid in the Oca?

    Have you eaten them already Frosty!
    Oh Drat - I've just had to eat one It was the smallest - honest. Like a sugary radish - juicy but not lemony. Maybe because they've been maturing for a few days?

    I've been tempted to try one. Will save them as might give a few to a woman on my allotment, who gave me some fruit canes yesterday.
