After cooking the mince filling, you can cool it in the fridge for 2 hours or even overnight. This will help stop the potato from weeping into the filling and makes spreading the potato easier. You can also pop the mince filling into the freezer while you make the potato topping.
Thicken the sauce to your desired consistency while cooking the filling. It will not thicken any more. The consistency that you pour it into the baking dish at, is the consistency that it will be when it is finished cooking.
If your potatoes are a bit watery, make sure that you drain them properly and that you allow the potatoes to steam as this will help decrease the amount of water in the potatoes when mashing.
Other vegetables can be used, such as grated zucchini, spinach or frozen mixed vegetables.
For a gluten free option, take out the plain flour and use a mixture of cornflour with a small amount of water instead. Also, check your Worcestershire sauce as it may not be gluten-free. If not, leave it out.
