Tip the strawberries into a large bowl.
Splash over the Cointreau, add the orange
zest and sift in the icing sugar, then give
everything a really good mix. Cover, then
leave for 1 hr or more for the juices to
become syrupy and the strawberries
to soak up some of the alcohol.
To serve, scatter the mint leaves over the
strawberries and give them one more good
stir, then spoon into individual glass dishes.
