You could be right SJ. I seldom had to buy fruit or veg - my students' families were mostly in the business of growing or selling them and would often bring me a crate of whatever was in season. But even on the odd occasion when I shopped for tomatoes they had that sweet/acidy flavour. They were all locally grown on the fincas around the village. I miss the tomatoes and oranges straight from the tree the most, but also harvesting loquats, persimmon and figs from trees locally that nobody else bothered with!
I have no idea about the variety Jayb. They were a bit bigger than the regular size tomato grown here and a tad less round, but I wouldn't call them beefsteak size.
My - How time flies! It is almost 17 years since I left Spain for Canada - and 14 since I landed here in the west country where for the first time since the 1980's I am growing my own fruit and veg again.
