Now I've come clean on that I have to say they taste delicious. The texture is firm and they're bursting with sweetness. Just add a dash of olive oil and a twist of salt. And they're great to look at on the plate.
Golden Sweet they're called and I've searched the catalogues but haven't found a yellow plum type like them.
Doing an internet search, following the suggestion in Bifurcated Carrots recent post, I found seed called Golden Sweet referred to as a 'gold grape' type. I suppose they look grape like as well. But at £2 for five seeds that seemed high.
Has anyone successfully saved seed from commercially raised varieties like this? The label doesn't tell me if it's an F1 variety and likely not to come true from seed.
Is there another variety available as seed you'd swear by?
