I think it’s also a lack of basic cooking skills in the generation that are now parents.
I was in Ireland 1979-1990 and at the start of that period most teenage girls knew how to make buns and apple tarts, soda bread and boiled veg plus potatoes in any form. They helped with Sunday dinners. Then, as students we lived on sandwiches, chocolate bars, Tayto and the odd apple from the newsagent, all day fry ups, tea and toast. Maybe a spag bol if we were feeling adventurous. Later on it was takeaway salad bars, coffee shops or chip shops.
So the skill of cooking became middle class with ambitious girl graduates my age taking evening classes in Italian or Ethnic cooking.
Even the Irish TV cooks bringing back traditional bread etc are painfully middle class…
I was back in Dublin 2 years ago and I was gobsmacked when I saw people in Merrion Square bringing home takeaway in polystyrene boxes FOR LUNCH. The lack of time and skills just can’t compete with a spice box!
Then there’s the empty calories and health effects from socially acceptable binge drinking.
