Mangoes. Pakistani mangoes in summer, eaten on the roof with my brothers, juice to the elbows, arguing about which variety is best, which is a serious national debate. We can buy imported ones here sometimes, at a price that made my wife laugh out loud in the shop, and they're good, but they taste of the airport.
What we did instead was build a small network. There's one halal butcher in our area who also sells spices and lentils, and he knows which days the good produce arrives. A family from Lahore two streets away shares the order when someone's relatives send a box of mangoes in season, so twice a summer our kids get the real thing and understand why their father gets emotional about fruit.
And my wife now makes nihari on Sundays that is honestly better than the restaurant version at home. It takes all day and the whole house smells of it. Don't tell my mother I said that.
