Im very lucky as my fiance does all the cooking in our house and he is a fantastic cook takes after his mum which is great, he looks after me very well

ive never tried to cook at his parents home as i get weighted on hand and foot even when i try to help im told to sit down and relax as awkward as this makes me feel its so sweet to see how his family run around after me like royalty.
I am a great fan of cous cous and various foods, but i must say that my fiances parents are not well off and his mum is one of the best cooks i have ever met, i do not see how being wealthy or poor can at all affect the technique or taste of food?? arent all vegetables and food the same no matter where they are bought from?
