Cook the
apples with 15g/1/2 oz butter, 15g/1/2 oz demerara
sugar, lemon zest, cinnamon and
nutmeg for 10 to 15 minutes, until the apples
are soft enough to beat to a puree.
Melt
the remaining butter in a flying pan over a low
heat and add the breadcrumbs
and the remaining
demerara sugar.
Toss everything until the crumbs
are coated, and continue tossing while you fly
the crumbs until golden brown.
Spread
one third of the crumbs in a 1.2 liter/2pt
ovenproof dish and add half the apple
puree in an even layer.
Add another third of the
crumbs and the remaining
apple, then finish with a layer of crumbs. Bake
for 20 minutes, or until crisp and golden on
top.
