Japanese Jelly Dessert (Awayuki)

Serves 6.
Ingredients
1 1/2 sticks kanten or 4 teaspoons agar-agar powder
250 g/8 oz/1 cup sugar
3 tablespoons strained lemon juice or fruit flavoured liqueur
2 egg whites
lemon slices or strawberry fans for decoration
Directions
If using kanten, break sticks into pieces and soak in 2 cups water for
30 minutes, then bring to boil and simmer until completely dissolved.
If using agar-agar powder, sprinkle evenly over surface of 2 cups water
in a saucepan and stir until it boils and dissolves. Add sugar and stir
to dissolve. Remove from heat and stir in lemon juice.
Whisk egg whites in a clean, dry bowl until stiff. When agar-agar
mixture is still slightly warm add it to the egg whites, mixing well.
(Do not let it cool too much or it will set before you can mix it into
the egg whites.) Pour into a mould or individual dishes and leave to
set. Chill and decorate.
