Still experimenting with recipes for Xmas day - latest try was leek and mushroom pie, not bad; it is definitely a contender. Helps that it is very quick and easy!
The sherry would have taken it to a different level cookie, alcohol in cooking is great!
Mab, here is the recipe for the leek and mushroom pie - it can easily be made in advance and can be quite firm or softer, depending on how you make the sauce component. The recipe is really a semi-pie (I don't know the 'correct' culinary name for it!) - just the topping is pastry https://wallflowerkitchen.com/creamy-leek-mushroom-pie-vegan/
