Toheroa Soup
Toheroa soup is a delicate and highly prized New Zealand delicacy, traditionally made from the toheroa clam, a large surf clam native to New Zealand's beaches. Due to overfishing, fresh toheroa are now rare and protected, so canned toheroa or even clam substitutes are often used. The soup is known for its subtle, unique flavor.

- 2 oz Flour

- 4 cups Fish stock or clam juice
- to taste Salt and pepper
- 2 large Egg yolks
- 1/2 cup Whipping cream
- 1 tsp Lemon juice
- 1 tsp Parsley(finely chopped, for garnish)
