Thread: Boiling stags heads, why do some come out yellow and some white?

So over the years I've boiled out a few stags heads. Sometimes they will come out of the pot bone white and other times yellow like they are full of grease.

I do the same thing everytime, in the pot with a bit of dishwash liquid and boil for about 1 1/2 hours.. then out and waterblast. The only thing I could think of was that I left the red for about a week before boiling vs the sika doing 3 days later.

Here's a couple of examples
Redstag from the roar came out nice and white:


Couple of sika from the weekend yellow


Any suggestions?
