Make double quantities of the
crumble topping, then freeze it
ready for next time. There’s no need to
defrost it first.
Heat oven to 200C/fan 180C/gas 6. Place
the plum halves, skin side down, in the base
of a large heatproof dish. Drizzle over half the
maple syrup and roast for 10 mins.
Meanwhile place the butter, flour, oats,
sugar and cinnamon in a bowl and rub the
butter into the mixture until you have rough
crumbs. Stir in the almonds, then sprinkle
over the plums. Drizzle the top with the
remaining maple syrup and bake for 15 mins
until the top is golden. Serve with custard.
