Cook the edamame according to package directions (boil or steam).
Drain well and let it cool to room temperature.
Combine the cooled edamame, water, lemon juice, soy sauce, tahini, sesame oil, garlic, ground coriander, and salt in the bowl of a high-powered blender or food processor.
Blend on high speed until the mixture is completely smooth and creamy. If the blender is struggling, add more water, 1 tablespoon (15 ml / 0.5 fl oz) at a time, until it blends easily.
Taste and adjust seasoning if necessary, adding more salt or lemon juice as desired.
Transfer the hummus to a serving bowl.
Garnish with whole edamame and a drizzle of sesame oil, if desired. Store leftovers in an airtight container in the refrigerator for up to 4 days.
Don't be afraid to add more water. If your blender is struggling, add water one tablespoon at a time until you reach your desired consistency.
