wash the cherries to get rid of all the gunk then dry them on kitchen
paper, and roll them in a LITTLE flour. the cherries usually sink to
the bottom of the cake because the gunk makes a heavy fruit heavier.
at school we were taught to chop them up before washing and when dried
pop them in a plastic bag and add a little flour. give the bag a good
shake to evenly coat fruit and that should do the trick.
