When making Sri Lankan food away from home Miss Wijetilleke calls her mum for help if she gets stuck.
"She'll fix it over the phone," she said
“I don’t know how she does it."
Miss Wijetilleke said her mum does not need exact measurements, she just eyeballs it and it is always “yum”. Cooking Sri Lankan food reminds Miss Wijetilleke of her childhood meals.
“My mum used to make four curries for lunch, and it was always different … I do miss lunch at home,” she said.
