So I went to Europe and Russian markets trying to find gardenia massimo type of bread

Couldn't find.

The EU bakes bread in a big bun and sold in slices which are oval from small to big then to small. If u don't finish it on the same day, it hardens like rock

The white flour area is not chewy like gardenia massimo as well.
What did our bread company put.
It's hard to find an equivalent

Even our local pastry shops. Slogan and motto say like European pastry but ntg like it. (Lavender)
All fluffy sugary and soft on inside

I am not sure. Usually if left long wrapped with rubber band also Lao Hong

Anyway French fries mcd in rus and EU is super crisp and lasts after 6 hours. Whereas our fries become lembik
There's a also a rumor mcd Europe uses pork lard mixed to cooking oil for deep fry French fries. Another reason my Muslim colleagues don't support mcd overseas apart from Palestinian bullet to yahood issue
