Step 1

Whisk eggs and olive oil in a bowl until combined; stir both amounts of club soda and salt into egg mixture. Mix matzo meal into wet ingredients to form a workable dough; if mixture is too wet, stir in 1/4 cup more matzo meal. Cover and refrigerate for 30 minutes.

Step 2

Bring water to a boil in a large pot. Wet your hands and form matzo ball dough into walnut-size balls. Gently place matzo balls into boiling water. Reduce heat to low, cover, and simmer matzo balls until tender, 25 to 30 minutes.
