What is the main vegetable in Swedish raggmunk pancakes?

The main vegetable in Swedish raggmunk pancakes is potato.

Raggmunk is a Swedish potato pancake made with shredded raw potato folded into a batter, then fried until crisp and golden. The potato gives the pancake its distinctive texture and makes it substantially different from ordinary Swedish pancakes, which are closer to thin crêpes.

Raggmunk is traditionally served with fried pork or pork rinds and lingonberry jam. The salty, rich pork and sharp, tart berries balance the mild starchiness of the potato. A closely related dish is rårakor, a crisp potato pancake made without the flour-based batter.

A common mix-up is to treat raggmunk as a generic vegetable pancake. Other vegetables may occasionally appear, but potato is the defining ingredient. It is also distinct from Swedish oven pancakes such as ugnspannkaka and fläskpannkaka, which use an egg-and-milk batter and are baked rather than pan-fried.
