- Combine all the spices in a heavy plastic resealable bag (except the prague powder) and crack the whole seeds and spices by lightly pounding with a heavy rolling pin.
- Place the short ribs in a large bowl with half the spices, salt, prauge powder and cover with cold water. Once well mixed, cover and refrigerate for 24-48 hours.
- Drain the brine liquid and pat the short ribs dry, brushing off any spices.
- Place the short ribs and the other half of spices in a large heavy bottomed pot over medium high heat and add the onion. Bring to a boil then lower the heat, simmer for 1 hour.
- While the short ribs simmer, mix together the sour cream and wasabi. Set aside.
- Add the carrots and cook for another hour. Add the cabbage and simmer for an additional 15-20 minutes until everything is tender.
- In a separate pot, cover the potatoes with cold water, a heavy pinch of salt and cook for 5-7 minutes until a knife point goes in easily. Drain the potatoes, rinse, and cut in half.
- Add the potatoes back to the pot over medium heat. Add the cream, salt and freshly cracked black pepper. Cook for 3-4 minutes, until the potatoes are coated and absorb the cream. Top with the chopped parsley.
- To serve, plate a few pieces of each of the vegetables, short ribs and top with the wasabi sour cream.
