Kale Matzo Ball Soup with Ginger Shiitake Broth

A vibrant twist on traditional matzo ball soup, this herbaceous version incorporates kale into both the fluffy dumplings and aromatic broth. Ginger, shiitake, fennel, and lemongrass infuse the stock with complex, warming flavors while sesame and coriander add depth. The matzo balls stay tender from seltzer and olive oil, creating a lighter texture than classic recipes. Ideal for Passover seders or as a nourishing soup when you want something special. This version celebrates green vegetables and global aromatics while honoring Jewish culinary tradition.

Tips
Wet your hands frequently when forming matzo balls to prevent sticking and ensure even, light dumplings that cook evenly in simmering water.
Strain the stock through cheesecloth for a clearer, more refined broth with less sediment from the aromatics.
Make the stock and matzo balls up to one day ahead, then assemble and serve hot for a quick final step.
Good to Know
Refrigerate stock and cooked matzo balls separately in airtight containers for up to 4 days. Freeze stock for up to 3 months; freeze cooked matzo balls for up to 2 months.
Make stock and matzo ball mixture one day ahead. Form and cook matzo balls up to 4 hours before serving; reheat gently in simmering broth.
Ladle hot kale broth into bowls with at least 3 matzo balls per serving. Garnish with fresh cilantro and a squeeze of lime if desired.
Common Mistakes
Over-mix matzo ball batter to avoid tough, dense dumplings; fold gently
Skip refrigeration of batter to avoid balls falling apart; chilling is essential for structure
Don't over-simmer matzo balls to prevent them from absorbing too much water and becoming waterlogged
Substitutions
FAQ
Can I make matzo balls without seltzer?
Yes, use water instead, but they will be denser. Seltzer adds carbonation that creates lighter, fluffier dumplings. Still delicious and traditional.
What if I don't have fresh kale?
Frozen kale works well when thawed and squeezed dry, or substitute spinach. Frozen purees easily. Use same amount unless packaging lists different yield.
How long can I keep matzo balls in broth?
Store separated for best texture; matzo balls soften if left in broth overnight. Keep together up to 2 days refrigerated, then reheat separately.
