Instructions
Place rinsed rice and lentils in a saucepan and top with 3 cups of water. Cover with a lid and place over medium-high heat. When it comes to a boil, reduce the heat to medium low and simmer for 18-20 minutes, until the rice is tender. Remove the lid, don't stir, take off the heat and set aside to cool.
Find a deep saucepan that will fit your entire cabbage, with some room to spare. Fill this pan with water until it's three-quarters full. Bring to a boil.
Fill a large bowl with cold water and add a few ice cubes. Turn the cabbage upside down and run a sharp knife around the core, then carefully shimmy it out and discard (I couldn't get my core out but by cutting around it, the process worked as well. Later on, I discarded the core).
When the water is boiling, add 2-3 teaspoons of salt and place the entire cabbage in the water, root-side up. Using tongs, submerge the cabbage and hold it there to keep it submerged. After 30-60 seconds, the outer leaves will begin to fall away. Remove them from the boiling water and place in the ice bath. Continue cooking until you have 12 leaves. Remove the remaining inner cabbage heart from the pan, (discard the core if you weren't able to earlier), finely chop the cabbage heart and set aside. Drain the cabbage leaves and allow to dry out.
Prepare the filling. Heat a large sauce pan over medium-high heat. Add 2 tablespoons of olive oil, along with the onion and cook for 2 minutes until softened. Add the kimchi or sauerkraut (along with any juices) and the chopped cabbage and stir for 8-10 minutes, until the cabbage is completely wilted and sweet. Turn off the heat and add the rice and lentils, vinegar, 1-2 teaspoons of salt and season well with black pepper. Fold everything together and taste again, adjusting the seasonings as needed. Set aside.
To make the tomato sauce, heat a large Dutch oven over medium-high heat. When hot, add 2 tablespoons of olive oil, along with the butter. When the butter is melted, add the garlic and stir to soften, about 1 minute. Add the tomatoes, along with 1 cup of water, sugar, and about 1 teaspoon of salt. Season with black pepper and stir to combine. Reduce heat to medium-low, cover with lid and allow to simmer gently while you make the cabbage rolls.
Preheat oven to 400F.
Remove the tough middle vein from each cabbage leaf by laying them on a flat surface and cutting a V-shaped notch to remove the thick part of the cabbage rib (but don't cut more than a third of the way into the leaf).
Working with one leaf at a time, with the uncut side closest to you, place 1/3 cup of filling in the center of the leaf. Fold the sides of the leaf tightly over the filling, then roll it up. Place it, seam-side down, on a large plate and repeat with the remaining leaves and filling.
Nestle the stuffed cabbage rolls, seam-side down, in a single layer in the tomato sauce. Sprinkle with sea salt and drizzle with oil. Cover with a lid (or foil) then place in to oven and cook for 15 minutes. After this time, remove the lid and increase the temperature to 450F. Cook for another 10 minutes, until the tops of the cabbage rolls have some golden color.
Remove from the oven and allow to cool for a few minutes, before topping with dill and serving.
Notes
These cabbage rolls can be fully prepped the day before: assemble the rolls, top with the sauce and cover tightly. Store in the fridge until ready to bake; remove from the fridge 30 minutes before baking.
