For a true zero-carb result, use a verified zero-carb chicken broth and check labels on tamari, soy sauce, coconut aminos, and hot sauce for hidden sugars or starches. The key to elegant egg ribbons is keeping the broth just below a full boil and pouring the eggs slowly while stirring gently in a single direction. This soup is best enjoyed fresh, but leftovers can be cooled and stored in an airtight container in the refrigerator for up to three days, then reheated gently over medium-low heat without boiling to preserve the tender texture of the eggs. Feel free to customize each bowl with low-carb additions like spinach, extra green onions, or a touch of chili oil while keeping total net carbs within your keto goals.
