1. Remove the cucumber seeds. This helps create a meatier, less watery salad - English cucumber are less watery, but still benefit from a light scooping of the seeds with a teaspoon.
2. Spice it up. Drizzle over some chilli oil at the last minute for a splendid combination of spice and cool in every bit.
3. Try black vinegar (Chinkiang vinegar) - for a deeper headier sourness. It can add a lovely complexity to the dressing.
4. Toast your sesame seeds at home. Dry toasting your sesame seeds at home will enhance the flavour no end. You CAN buy pre toasted, but they've already lost the bulk of their flavour. See for yourself the wonderful difference of toasting at home.
