RECIPE FOR MATZOH BALL SOUP RECIPES

Steps:

• Wash the chicken with water and place in pot. Cover with water and bring to a boil over high heat, skimming off bubbling foam as it forms. Add celery, carrots, onion, herbs, salt and pepper and simmer, half-covered at lower heat, for at least 45 minutes, until the chicken seems done. The chicken will come away easily from the bone. Pour soup through strainer to get a clear broth. Let cool. When broth has completely cooled, skim off the fat and save for the matzoh balls. 
• In a mixing bowl, mix together 4 eggs and 4 tablespoons chicken fat. Stir in the matzoh meal and salt. Add 1/4 hot water. Cover and refrigerate for at least 1 hour. Form the matzoh dough into balls the size of walnuts. Bring the salted water to a boil. Add the matzoh balls, cover, and cook for 20 minutes (don't even peek!). Bring the chicken broth to a simmer. Remove matzoh balls from hot water with a slotted spoon and add to the simmering chicken broth just a few minutes before serving.

Steps:

• Bring all ingredients and 12 cups cold water to a boil in a very large (at least 12-qt.) stockpot. Reduce heat to medium-low and simmer until chicken breasts are cooked through, about 20 minutes.
• Transfer breasts to a plate (remaining chicken parts are strictly for stock). Let breasts cool slightly, then remove meat and return bones to stock. Shred meat. Let cool, tightly wrap, and chill.
• Continue to simmer stock, skimming surface occasionally, until reduced by one-third, about 2 hours. Strain chicken stock through a fine-mesh sieve into a large saucepan (or airtight container, if not using right away); discard solids. You should have about 8 cups.
• DO AHEAD: Stock can be made 2 days ahead. Let cool; cover and chill. Keep reserved chicken meat chilled.
• Mix eggs, matzo meal, schmaltz, club soda, and salt in a medium bowl (mixture will resemble wet sand; it will firm up as it rests). Cover and chill at least 2 hours.
• DO AHEAD: Mixture can be made 1 day ahead. Keep chilled.
• Bring chicken stock to a boil in a large saucepan. Add carrots; season with salt. Reduce heat and simmer until carrots are tender, 5–7 minutes. Remove from heat, add reserved breast meat, and cover. Set soup aside.
• Meanwhile, bring a large pot of well-salted water to a boil. Scoop out 2-tablespoonful portions matzo ball mixture and, using wet hands, gently roll into balls.
• Add matzo balls to water and reduce heat so water is at a gentle simmer (too much bouncing around will break them up). Cover pot and cook matzo balls until cooked through and starting to sink, 20–25 minutes.
• DO AHEAD: Using a slotted spoon, transfer matzo balls to bowls. Ladle soup over, top with dill, and season with pepper.
