Skim Forming on Veal Stock During Reduction

[schoenfelderp]

I made a first extraction for stock from veal bones, I made a remouillage, and now I'm combining the two and reducing as per TFL instructions. Every 10 minutes or so a skin forms on the stock as its reducing. Should I be skimming this skin (i.e. is it considered an impurity), or should I be breaking it up back into the stock?

Parboil them first next time and then make your stock with a fresh lot of water.

[schoenfelderp]

Yup, blanched first to remove impurities.

Skim it away.

[twyst]

Skim it off.

what does it look like? I would guess it's just a consequence of a lot of gelatin in the stock, kind of like how a cooked pudding will form a skin

[primebeefisgood]

You are right, Girl. If it is skimmed off every time it forms, you will soon have no stock. Don't worry about it.

[schoenfelderp]

Hmm I'm not sure, the stock was extremely thickly gelled when cooled.

[calny]

I'd skim it off. I'm not sure what it is, but I was taught to skim it off. If you have the cooking vessel slightly off center of the burner, the skin will collect on one side of the surface. This makes it easier to skim off.

Not a professional chef, but I would taste it to see what exactly it is.

[schoenfelderp]

I think it may be that I didn't do a good enough job skimming during parts 1 and 2 and its just fat that I don't want emulsified into the stock but I'm not sure
