1️⃣ Blend the Fish Mixture:

1. Combine ground fish, minced onion, eggs, matzo meal, sugar, salt, and white pepper in a mixing bowl.
2. Stir until the mixture becomes smooth and cohesive.
3. Form into oval-shaped patties, roughly palm-sized.

2️⃣ Build the Broth:

1. In a large pot, add water, fish bones (if using), onions, carrots, celery, bay leaf, salt, and peppercorns.
2. Bring the mixture to a gentle simmer, allowing the flavors to meld.

3️⃣ Poach the Patties:

1. Carefully place the fish patties into the simmering broth.
2. Cover and let poach gently for 1 hour, maintaining a low heat.

4️⃣ Cool & Serve:

1. Remove patties with care and let them cool.
2. Strain the broth, discarding solids, and save it for serving.
3. Plate the patties, topping each with a poached carrot slice and a dollop of horseradish for a classic finish.
