Deglaze with about 250mL of the beef/lamb stock for a few minutes until reduced.
550 ml Beef/Lamb Stock
Add in bay leaves and the rest of the beef/lamb stock. Turn to low heat. Cover and simmer for 40 minutes.
2 Bay Leaves
Mix in the frozen peas and cover to cook for another 10-15 minutes. Season with salt & pepper to taste.
1 cup Frozen Peas, Salt & Black Pepper
While the mince filling was cooking, bring a large pot of water to a boil and season it generously with salt. Cook the potatoes for 12-15 minutes under softened.
1 kg Maris Piper Potatoes
Remove the cooked potatoes from the pot. Season with salt & black pepper and add in milk, butter, and cheddar cheese. Mash everything together until smooth.
1 cup Cheddar Cheese, 4 tbsp Whole Milk
Then add and mix the two yolks into the mash.
2 Egg yolks
Preheat your oven to 200°C.
Bring out a large oven dish and spread the mince into a layer. Top it with mashed potatoes and smooth it out. Use a fork to score a few lines on the mash. (Tip: if you want to make the pie look pretty, use a piping bag to pipe the mashed potatoes on top of the mince)
Put the dish into the oven and bake for about 30 minutes until the top is golden.
Allow to cool down for 10-15 minutes, then serve warm with gravy.

Notes
Adding chillies is completely optional. You can omit it if you don't like any hints of spice.
Traditional Shepherd’s Pie uses a dash of red wine to deglaze when cooking the meat. For halal diet, I use a dash of beef or lamb stock instead of alcohol.
To key to getting a rich flavour & moist texture from the mince is keeping it at low heat when simmering the meat.
After simmering, the liquids should have reduced and the mince should turn out to a thick & moist consistency. If the mixture is still rather liquidy, cook for a little longer until it slightly reduces. A sloppy meat base wouldn’t be able to hold up the pie and may even collapse when serving.
Use floury potatoes to make the mash, e.g. Maris Piper or King Edward potatoes or Yukon Gold & Russets for Americans. Avoid using waxy potatoes such as baby potatoes, white potatoes, red potatoes, etc. Waxy potatoes would result in a very gummy mash which is not ideal.
Watch out for the consistency of your mashed potatoes. You’d want to aim for a fluffy but firm texture so that the shepherd’s pie wouldn’t turn out sloppy.
Adding egg yolks to the mash is a technique introduced by Dominic Chapman, featured on Great British Chef. This is to give the mash layer a golden crust & glossy finish,
