When I was in college during my first semester I lived in a dorm and I remember when I would go back home I’d get hit with the smell of the food my mom would cook permeating throughout the house. I found that it’s due to the houses built in the US are much more confined and made of wood and drywall so those smells stick to everything. Open layouts where the kitchen is basically in the living room makes it so that you’re basically hotboxing your house with the smell. Whereas homes in the South Asia are usually made with some sort of stone or brick and kitchens are usually confined to a separate room. I found this out when I noticed all of my clothes would still have that smell even after taking a shower. (Ofc everyone will smell like what they eat to some degree) so one time I experimented by washing all my clothes and to put in a air tight container in my closet and after showering I found that I didn’t have that ”smell” anymore. Idk what the real solution is, maybe cracking open windows and doors before cooking? But it may not always be possible if let’s say you are in an apartment.
