Foraging as a child

JJB, Maybe that Thailand vine was Hablitzia/Caucasian Spinach or Malabar Spinach https://worldcrops.org/crops/malabar-spinach .

Don't think so but maybe, to be honest as a youngster I didn't pay much attention, the cook foraged (with me as helper) and then cooked it up for me.  I must have reeked of garlic in those days, but then so did everybody else    I seem to recall the vine was much like that bindweed lookalike you were discussing a few days ago but I couldn't be sure.
