About this recipe: This is an adaptation of my mother's recipe. I changed the recipe for my boyfriend who is a vegetarian. I had a Guinness® pie at a pub and it reminded me of how much I love them and I decided he was missing out on the joy!
Note that Guinness® may not be 100% vegetarian, due to a fish byproduct used in the brewing process. You can substitute a different stout that is vegetarian, if desired. Similarly, find vegetarian Worcestershire sauce or omit it for a truly vegetarian pie.
Made it vegetarian. To make this recipe completely suitable for vegetarians just use a strong Ale instead of the Guinness and ensure a vegetarian Worcestershire sauce is used (as many contain anchovies). Alternatively leave the Worcestershire sauce out completely as this still makes a delicious pie. - 17 Feb 2011
I used Quorn steak strips for this which worked really well. Taste is great but next time I'll just use the pastry just as a lid as the bottom layer made it slightly stodgy and had absorbed lots of the lovely juice by day 2 – would probably use slightly less potatoes (or smaller ones) and slightly more mushrooms next time too. Also used a stong ale and held off on the w sauce. Really tasty winter warmer for both meat eaters and veggies. - 20 Oct 2011
