Cock-a-Leekie pot pie. You can top with mash or you could top with puff pastry. If you're not a parsnip fan you could sub turnip, tattie, carrot, or other root vege. NOTE: corn flour = American corn starch and you can sub sour cream for creme fraiche. This recipe is an excellent base upon which to experiment.
