Food Fad

It was a meal made by paupers.
From the poorest cut of meat.
Common vegetables for flavor,
spices for added heat.

It was tasted by the upper class.
Sold in shops owned by the low.
It caught on as grand cuisine,
for palettes in the know.

It became the latest thing.
Demand for it grew.
Now the paupers can't afford it.
And are eating cabbage stew.
