Ingredients

Look up any ingredients about which there are questions in the Index. I use kosher salt for which medium sea salt or gros sel may be substituted, large eggs, unsalted butter, black pepper fresh out of a mill, yellow onions, unless otherwise specified. The olive oil is extra virgin, but I save the strongest for adding to the soup once it is cooked. Always use extra virgin olive oil, but save the best for last—to add to cooked soup just before serving. Use tamari soy sauce if possible.
