Combine the cream, flour, sugar and diced
apricots in a large saucepan. Bring to a simmer
over a medium heat and cook, whisking until
thick, for 3 minutes.
Remove from the heat, add
the kirsch, then whisk in the egg yolks one at a
time.
Beat the egg whites in a mixing bowl until
stiff. Butter a small soufflé dish, dust with
sugar, and spread 50g/2oz of the apricot mixture
on the bottom.
Add about a third of the egg
whites to the remaining apricot mixture and
gently fold together. Repeat carefully folding
in remaining egg whites in two batches.
Spoon
over the apricot mixture in the soufflé dish.
Bake the soufflé for 12 to 15 minutes, until
lightly browned on top.
Dust generously with
icing sugar and arrange sliced apricots on top.
Serve immediately.
