Take mince meat out of the fridge and let come close to room temperature.
Dice the onion and mince the garlic.
Mix onion, garlic, milk and breadcrumbs in a bowl and let sit for at least 5 minutes.
Once the mixture has come together in to a sludge add the mince, egg, salt and pepper.
Stir it all together. I will do it using my hands but feel free to use a spoon, just make sure that everything comes together in a smooth batter.
Wet your hands with cold water and roll the mince batter into round meatballs. Place on a cooking tray, space apart.
Oven cook for 10 mins in the middle of the oven 180 degrees C fan (360F).
If using a frying pan, add some butter in the bottom of the pan and fry the meatballs on all sides until golden in colour.
