The traditional Christmas Watermelon? Kool....
lol.. not Christmas, only “Yalda”.
It’s summer in Australia (summer fruit).
Besides, typically in Persian cuisine, they use a mix of “hot & cold” food/fruit/vegetables to help with digestion. It’s about offsetting heat with cold, in what one consumes. Sort of a balance in diet.
