Brown the mince with the chopped onion on a thick bottomed pan.
Add the mince and onion to the slow cooker. Add in the neeps, tatties and carrots. Add boiling water to almost the top of your ingredients.
Add a teaspoon of salt and a pinch of pepper and a stock cube, or stock pot if you prefer a stronger taste.
Put the lid on and leave for 8 hours on low, or 4 hours on high.
If you want to thicken your hotpot, half an hour before the end of cooking, mix up cornflour with cold water and mix to a smooth paste. Add to your hotpot and fold in until it thickens. If you over thicken, add a little boiling water to fix it.
