What was that cherry stuff my mum used to put in the middle of chocolate cakes?

[BroccoliSpears]

Was it black cherry jam?

And could I put jam in the middle and chocolate butter icing on top?

It might have been canned balck cherries in syrup.

Possibly cherry pie filling in a can.

If it was the 70's it was the syrup from tinned black cherries thickened with cornflour.

Ahhhh - tinned black cherries. Yes. Jam would be sweeter and sharper.

It was indeed the 70s.

Now I need to remember what she put on top of the cake.
