Chicken – Which non penetrating method is recommended to check chicken breasts for done-ness when pan fried

I generally use about 1cm deep of olive oil when I'm making schnitzel which may or may not be the right oil but it works for me.

I generally find that if the oil is smoking, it's too hot so I tend to get it to a temperature that is very hot, but not smoking.

Once I get it to that temperature, I don't cook too many schnitzel's at once, generally 2 or maybe 3 max to a pan depending on how big your pan is.

The final thing is that you need to make sure you beat the schnitzel out nice and thin before you crumb it so it's only about 1/2 a cm thick when you're cooking it. This way it'll only take a minute or two to cook through and won't overcook the crumb.

I suspect the blackness comes from the spices you put on the chicken burning.

Try this technique I learnt from Jamie Oliver: Season your chicken as normal. Put the pan on a high heat until it's hot (not stupid-hot, just hot). Add olive oil and the chicken skin-side down. Cook for about 5 minutes.

Meanwhile, take a square of baking parchment or greaseproof paper big enough to cover the pan. Fold it in half until you have a 'folded fan' shape. Hold the point so it's roughly over the middle of the pan, and tear off any excess that goes over the side of the pan. Unfold and you should have a circle of paper. Scrunch it up, then run it under a cold tap and give it a shake.

Turn the chicken over, turn the heat to medium low, then place the wet paper (a 'cartouche') on to the chicken. Finally put a heavy pan lid (the lid from a casserole is ideal) on top. Cook for another 20 minutes.

The moisture in the cartouche helps keep the chicken moist and prevents it from burning. Cooking time will depend on the thickness of the breast, so do check it's cooked through before eating (cut it open and check it's not pink).
