Remove thick outer leaves and thick ribs from the cabbage.
Cut cabbage into quarters and remove the tough core from each section. Slice each quarter into 1-inch wide strips.
Place sliced cabbage in a large bowl and break up the large clumps. Cover cabbage with cool water then add white vinegar, swish it around, and let it soak for at least 15 minutes. Drain the soaking water, rinse cabbage with fresh water and drain again.
To a large pot with a lid, add butter, olive oil, seasoned salt, chicken bouillon cubes, garlic powder, onion powder, black pepper, and crushed red pepper flakes then put the drained cabbage on top.
Add 2 cups water and bring pot to a boil (uncovered) over medium-high heat .
Stir cabbage to distribute seasoning, then cover pot and reduce heat to medium-low. Simmer for 15-20 minutes, stirring occasionally until cabbage is tender. Check it frequently after 10 minutes and stop cooking once it gets to your desired level of tenderness. Don't overcook or the cabbage will get mushy.
Serve cabbage warm. Optional - Add a little apple cider vinegar and pinch of crushed red pepper flakes to your individual serving of cabbage for extra flavor
