What's this white stuff on chicken breasts?

[Gauri]

Hey everyone! I bought a bunch of frozen chicken breasts from a local shop for meal-prep and tried cooking them in a pressure cooker for the first time, just with pepper and turmeric. I plan to store them for different dishes later.

I'm not sure if I overcooked them or if the quality was off, but there was a white film all over the meat. Anyone know what that is? You all seem to cook chicken breasts a lot, so thought you could help.

Is it chicken malai?

[Navya]

It's just extra protein. Just eat it.

[Harendra]

Avoid using a pressure cooker. It can go above 90°C and overcook the breast, turning it into a chewy nightmare.

[Mayank]

That's protein breaking down under high heat and pressure.

[Advik]

It's just skin-fat residue, perfectly safe. Also, why are you boiling the chicken in the first place?

[Shankar]

It's basically chicken fat.

[Rohit]

I think it's fat?

That's just scum. When you boil chicken or make stock, a foamy layer rises once it hits a boil. You're supposed to skim it off with a ladle a few times for a clearer broth. It's harmless, though it can give a slightly muddy flavour.

The best way to prep chicken breasts is to butterfly them, pound them with a mallet, then marinate according to the portion size with any marinades you like and keep them on a tray in the fridge. Don't keep them more than three days; if you need longer, freeze them.

For cooking, heat a little butter and a few drops of oil or olive oil in a pan over high heat, brown one side, flip and brown the other, then add a splash of water, cover and steam on medium heat. Browning locks in moisture, and the steam finishes the cooking without drying it out. That's how I do it.

It's fat and impurities.

If you want to get rid of it, plunge the chicken into boiling water for about 45 seconds, then take it out and run it under cold water. Fill a fresh pot with water and boil the chicken there for eating.
