Service

Start: T+40m (03/22 1:40pm) | Duration: 5m

Ingredients Steps
1. Reheat via sous vide at 150°F until hot (~20 minutes). Hold at temperature for up to 60 minutes if absolutely needed (flavor will gradually dull over time).
  • 0.5 gram dried kombu, broken into small pieces
  • 100 milliliter water
2. Prep a "refresher" bag with dried kombu and water only
3. During the last 5–10 minutes (do not exceed 10 minutes) of reheating, add the refresher bag to the bath to to extract a light kombu infusion
4. Strain the refresher contents
5. Start by adding ~5–10% of the refresher. Adjust incrementally to taste until balanced (flat/dull → more refresher; too bitter → a small amount of refresher; too strong/ocean-y → dilute with water)
6. Serve hot in a tea cup
