Method
- Toast the sesame seeds in a dry pan over medium heat, shaking constantly, two minutes until they pop and turn one shade darker. Pull off the heat the moment they smell aromatic — burnt sesame ruins the dish.
- Pound 3 tbsp of the seeds in a Japanese suribachi (ridged mortar) until the oils release and the seeds turn into a coarse paste — about two minutes. Reserve the remaining 1 tbsp whole for texture.
- Whisk soy, sugar, mirin and dashi into the sesame paste in the suribachi until smooth. Taste — it should be sweetly nutty with a savoury back; adjust sugar if needed.
- Bring a large pot of water to a rolling boil. Drop in the spinach stem-first, count to twenty, then plunge into ice water. The leaves should be vivid green and still firm.
- Squeeze the spinach hard between your hands to extract all water, then chop into 4cm lengths. Loosen the bundle so it isn't a brick.
- Toss spinach in the sesame dressing in a mixing bowl until each strand is coated. Pile in small dishes, scatter the reserved whole sesame on top, and serve at room temperature. Best within an hour — the dressing thins as the spinach releases water.

Cultural Note
Goma-ae is the home cook's two-minute side dish — almost any green can stand in (green beans, broccoli, asparagus). The grinding of the sesame is the make-or-break step: pre-ground sesame paste from a jar makes a dish that tastes flat and lifeless, because the oils oxidise within hours of grinding. A suribachi is a Japanese kitchen workhorse, used for sesame, miso paste, dengaku-miso, and any number of small jobs where a blender is overkill.
