In the US it’s not crazy for kids maybe as young as 6 to make themselves sandwiches like a PB&J/Ham & Cheese either if parents have an emergency, or to take to lunch for themselves because parents didn’t have time. (Or you know, they’re neglectful)
So is there a go to food for children to make in other cultures?
Curry-pickled herring with raw onion and caper on rye is the first dish served on our traditional Christmas lunch. Served with snaps.
Fish generally don’t go to well in a lunchbox. The most common are mackerel in tomato with mayonnaise and cod roe with rémoulade, but most kids would frown at it. Also, it requires a fork and knife to eat. The traditional lunch box sandwiches are made to be eaten by hand.
I just found some random photo from the web. Apparently it’s difficult to find a photo of our common lunchbox hand-served-rye-bread-open-sandwiches. Most are of restaurant high topped “smørrebrød”, which also requires knife and fork.
