After the success of the blood clots, I felt confidently inspired to expand the theme by making up lime jelly with milk to create pus. It is hideously, fabulously realistic. I tend not to serve this on its own but rather dot the blood clots with it to evoke an attractive burst-boil appearance. But if you want some pus by itself, then maybe double the amounts below.
