Indian food uses a lot of onions. Learning to mince an onion is a pretty key skill and something worth mastering – not only so you can control the size of the onion pieces more effectively than a blender, but it also helps improve knife skills overall. Here’s how I do it.
Start by cutting the top off your onion with a sharp knife
Then, slice down the middle
The more horizontal slices you make, the thinner the mince – 2 slices (to make 3 segments) is usually plenty.
Next, make vertical slices from the root towards the head. Try to hold the onion together as best you can. Again, the thinner the slices, the finer the mince.
Finally, slice down the onion (while holding the onion together). Once again, The finer the slices, the thinner the mince.
Point your fingers straight down and slide the blade down your knuckles – this ensures the onion stays together and you don’t lose a finger.
Some people ask me how you can avoid crying whilst chopping onions – my answer: You Don’t! You suck it up, like a man – that onion died for your gastronomic pleasure, so the least you can do is shed a tear or two. In seriousness, much of the juice is in the root, so avoid cutting that bit – you can use goggles (if you’re that worried) or cook in a well ventilated room, which will help disperse the onion juice. Other tips include chewing a peppermint (not sure about this one) or having a pot of steaming water in the room that can help absorb the juices. Cooling the onions is also said to help, so stick them in the fridge for a bit before cutting them. Unfortunately, you don’t get used to it – I was my mum’s onion cutter when I was a kid and I still cry.
Finally, make any chops you want to make the mince finer.
Ta da, minced onion. Practice, practice, practice – the better your knife skills, the finer your onion will get. Start by doing 1 horizontal cut, 3 vertical cuts and then slicing the onion. Then add more slices into the mix to get finer and finer.
