I know what this mystery fruit is now. How did I find out? I ate it...well, after I cooked it. Yes, that is how I found out what this thing was. I used a sharp knife to cut it in half-- that in itself was none too easy!-- and I baked it. It was Tommy’s suggestion as he couldn’t tell what it was either. It was the only way to see what this mystery fruit could be. Once I pulled it out of the oven I knew straight away and did a forehead thumping DUH! Wonder if you can guess? Perhaps I’m the only dummy. No matter, I’m used to this sort of thing happening to me. Live and learn or in this case, garden and learn.So, now that you see it, what do you think it is? We're talking about the one on the right. I know the other is a pumpkin. I just put it there for contrast to help you out.
