A good old traditional meat and potatoes pie.
Fry the onions for a couple of minutes over medium - high heat until it has begun to soften.
Add the carrots and celery and continue to fry for a few more minutes.
Add the garlic, rosemary and fishy thing (anchovies / fish sauce) and cook for a few more minutes until everything smells great.
Set the vegetables aside. Return the pan to the meat and fry the meat in batches, seasoning as you go. If too much fat accumulates - remove it.
Add tomato purée and wine. Once reduced - add the stock and Worcestershire sauce.
Simmer with the lid on for 45 mins.
Add the onion, carrot and celery mix from earlier and allow to reduce for approximately 20 mins.
Season and set aside.
Boil and mash potatoes. Mixing in your chosen creaming ingredients.
Add the peas to your meat mixture.
Pour into a container suitable for going in the oven.
Preheat oven to 190°C / 375° F / Gas 5.
Spread the mash on top of your pie, making pretty patterns with your fork and brushing with melted butter.
Bake for 30-40 mins until the juices are bubbling up from under the potato. Finish with a blow torch if your top isn't crispy enough for your taste.
