Can I make this soup ahead of time?
Yes. Prepare through the final simmer, cool, and refrigerate up to 4 days. Reheat on the stovetop over medium heat, adding the lemon juice just before serving.
What type of cabbage works best?
Savoy cabbage is recommended for its tender leaves and mild flavor, but green cabbage works equally well if that's what you have on hand.
Can I substitute ground beef?
Ground pork, ground turkey, or ground lamb are solid swaps. For vegetarian, use cooked lentils or crumbled tofu in place of the beef.
How do I know when the rice is done?
The rice should be tender and the vegetables soft, usually 20–25 minutes of simmering after the rice is added. Taste a grain of rice to confirm doneness.
Is lemon juice essential?
It's optional but recommended. The acid cuts through the richness and brightens the tomato-forward flavor. A splash of vinegar works as a substitute.
