STORAGE AND FREEZING INSTRUCTIONS: Store the ramen broth in airtight containers in portions (remember you’ll need 2 cups/500 ml per serving.) Refrigerate until cold. You can keep the ramen broth refrigerated for up to 4 days, or freeze it for up to 1 month (or more, if you have a chest freezer.)
A layer of fat will float to the top of the ramen broth and harden as it cools. Do not discard the fat. This fat is what makes this broth so delicious and flavorful. This fat will melt back into the broth as you reheat it before serving.
If you have limited storage capacity, you can save on space by simmering the broth further, until it is reduced by half. This means that you’ll store 1 cup (250 ml) broth per portion. Make sure to add a note on the container to remember to stir 1 cup (250 ml) water back into the broth (per portion) as you reheat it for service.

Notes
HOW TO REUSE KOMBU: Recycle the kombu you used in the broth by turning it into a quick salad. Sliced the steeped kombu pieces thinly and transfer to a bowl. Drain and rinse a small can of bamboo shoots (6.7 oz/199 ml). Pat dry and add to the kombu. Add 1 tbsp (15 ml) toasted sesame oil, 1 tbsp (15 ml) rice vinegar, 1 minced garlic clove, 1 tsp (5 ml) Japanese soy sauce, 1/2 tsp (2 ml) granulated sugar, 1/2 tsp (2 ml) crushed red peppers, and a pinch of salt. Toss to combine. Enjoy right away, or refrigerate in an airtight container for up to 2 days.
