Rumble and Thump

Take a peck of purtatoes, and put them into a boyne — at them with a beetle — a dab of butter — the beetle again — anither dab — then cabbage — purtato — beetle and dab — saut meanwhile — and a shake o’ common black pepper — feenally, cabbage and purtato throughither — pree, and you’ll find ’em decent rumbledethumps.”

Rumbledethumps is a traditional dish from the Scottish Borders. The main ingredients are potato, cabbage, and onion. Mashed potatoes are mixed with lightly sautéed shredded onions and cabbage, seasoned, topped with grated cheddar, and baked until the cheese is melted and golden brown.

Shameless Addition of New Character

Rumbledethumps can be served as a main vegetarian dish or as a side dish. Now, imagine turning it into a crustless pie (like Sheppard’s or Fisherman’s). Imagine cooking tender lean proteins under the rumbledethumps blanket, which can protect tender meat, poultry, or seafood from direct dry heat. Every drop of moister and flavor is caressed and saved. Seafood was my number one choice, and salmon species from Northern seas looked very appropriate for the Scottish menu.

When cooked, Arctic Char, Scottish Salmon, and Sockeye Salmon taste slightly different, yet delicious. The fattiest out of three, Arctic Char is my favorite. This version of Rumbledethumbs is part of my tasting event My Food Travels: Scotland.

Another interesting variation I made with giant scallops (sliced in half) and ramps compound butter. Scallops release some juice during the cooking, which is absorbed by mashed potatoes. It somewhat changes the texture of the whole dish. After our group discussion about this dish in Facebook, I wanted to try brussel sprouts instead of regular cabbage, and liked it a lot. Bottom line, there is definetly some space for creativity to apply when playing with Rumbledethumbs recipes.
