Opo fruits have to be used before mature, or, yes, the large core is “seedy” almost like an apple core, the skin is tough, and what remains between the two may get pithy. Young, it’s all “tender and mild”, like a very oversize young cucumber.

Fun.
It never occurred to me, but I suppose a well watered "temperate" plant in the heat does better when conditions include a bit of a breeze: Evapo-transpiration should keep the plant cooler. Of course, if it dries up, that's another story...
I do note that keeping my plants' soil (or pots) shaded or very well mulched (if just in the ground) definitely seems to help them out in these conditions. (I don't really have a practical way to shade the upper portion of my tomato plants' foliage when some are over 6 ft. tall / high. But, shading the soil they are rooted in is pretty easy. :-)
