Put
the sugar and water into a small saucepan and heat
gently to dissolve the sugar, then boil rapidly until
the thread stage is reached. The thread stage
temperature is
107°C
(225°F) on a sugar thermometer: to test without a
thermometer, remove a little of the syrup with a small
spoon and allow it fall from the spoon on to a dish. The
syrup should form a fine thread.
-
Reserving 4
strawberries for decoration, slice the remainder and put
them into a food processor or blender with the syrup.
Blend for a few seconds, then pour the puree into a
bowl.
-
Stir the
yogurt into the strawberries and pour into a 1.2 liter/2
pint freezer proof container. Freeze for about 2 hours,
stirring once or twice, until mushy.
-
Spoon
the strawberry mixture into a large mixing bowl and put
the egg white and cream into two slightly small bowls.
-
Using an electric whisk, beat the egg white until it is
stiff but not too dry. Whisk the cream until it forms
soft peaks, and whisk the strawberry mixture until
smooth. There is no need to wash the whisk in between if
you keep to this order.
-
With a large metal spoon, turn
the egg white and cream into the strawberry mixture and
gently fold all three together until smoothly blended.
-
Return to the container and freeze for about 3 hours
until the ice cream is setting round the edges. Spoon
into a bowl and whisk again until smooth and light.
-
Pour the ice cream back into the container, cover and
freeze for at least 6 hours. Transfer the ice cream to
the refrigerator about 40 minutes before serving to
soften
slightly.
-
Scoop or spoon the ice cream into glasses and
serve decorated with the reserved strawberries.
