For people coming from colder countries, there are certain vegetables used in typical national dishes, which only grow in colder climates. For example, most Brassicas only grow in cold climes, and lots of kale requires a frost to grow well. At the point when Manila is having frosts, recreating a typical Scandinavian dish is probably the least of your worries, so growing locally is likely out...
Is it possible to buy cold climate vegetables in Manilla? Is there perhaps a special market where you can go which specialises in importing vegetables like that? (I guess probably grown and brought in from Japan or northern China)
