Simmered Aubergine (Eggplant) with Ginger Sauce (Nasu no Ohitashi)

Ingredients

1 medium aubergine (eggplant) - about 250g (9oz)

Ginger-Soy Sauce:
1 x 1-inch (2.5cm) cube fresh ginger, peeled and finely grated
1 tbsp good-quality Japanese soy sauce (eg Kikkoman)

Directions

1. Cut the stem end off the aubergine, but don't trim the blunt end.
Cut the aubergine in half lengthways, then cut each piece across once so as to make four quarters of roughly the same size - you should cut much nearer the blunt end.
Bear in mind that the stem ends seem to lose more size in cooking.

2. In a pan wide enough to take all four pieces in a single layer, bring 600ml (20 fl oz, 2 1/2 cups) water to the boil.
Add the aubergines, skin side down, and reduce the heat.
Simmer for about 5 minutes, turning after about 3 minutes, until soft but not mushy (test by pricking with a fork).

3. Drain the aubergine pieces and cool on a plate, skin side up (don't throw away the remaining liquid; use it to make stock).
More liquid will come out as they cool; when cool enough to handle, press gently with your hand to squeeze out water without crushing the aubergine.
Avoid squeezing out too much - the aubergine should still be somewhat moist.

4. When cool, slice each piece lengthwise into 1/8 inch (1/2cm) pieces.
Arrange slices casually on small dishes or saucers.
Mix ginger-soy sauce and spread on top of the aubergine.
