Slliced Apple question

[GnocchiNineDoors]

Planning on making a salad as part of a picnic tomorrow - Feta, Beetroot and Apple, YUM. But, ill need to prepare it a good few hours before we eat it.

Are the apple slices likely to go brown when allready in the salad?

There's a theory that if you dunk them in lemon juice they won't go brown. Never tried it myself though.
When I make fruit salad, the juice of the oranges seems to stop the pears and apples going brown.

Lemon juice works. DD has sliced apple with a squirt of lemon juice in her lunchbox every day.

Grand, ill lemon them up and make the salad before we go.
