Popeye spinach

Bring a large pan of water to the boil with the salt, add the spinach and blanch for 1-2 minutes. Drain, run under cold water and drain again; cool. When cool enough to handle, squeeze out the excess water.

Meanwhile, toast the sesame seeds in a dry frying pan for 1-2 minutes until light golden and fragrant; tip onto a plate to cool. Transfer to the small bowl of a food processor and whizz to a fine powder. Put the sesame powder in a serving bowl with the sugar and soy sauce; mix well. Toss the spinach in the dressing to serve.
