2 small thin-skinned oranges, c 375 g
6 eggs
1 tsp baking powder
1/2 tsp baking soda
200 g ground almonds
250 g caster sugar
50 g cocoa
Put whole oranges in a pot with cold water, bring to boil, simmer 2 hours. Drain, halve, remove pips, pulp the lot in the food processor, allow to cool. This much can be done the day before.
Add remaining ingredients to the food processor and run until combined but still a little lumpy. Pour into a buttered and lined 30 cm tin. Bake in a 180 ' C oven for about an hour. Check after 45 minutes, cover with foil if top is in danger of burning.
Cool in tin then turn out. Decorate with additional orange peel if desired.
