I've revived my old Cheesecake recipe and it has NO TOLERATED ingredients making it suitable to Attack / strict PP days in Stab!
250 gr Tub Quark
1 pot (125gr) vanilla yoghurt (WW or use plain and up the splenda and vanilla a bit)
1.5 TB Splenda (to taste)
tiniest pinch of salt
1.5 TB Agar FLAKES
1/2 ts Vanilla flavour
1/2 ts Lemon flavour
Mix all well and pour into silicone cake mould - I used a loaf tin one as that's all I've got.
Bake at 160C for about an hour.
This will rise up and go golden brown, that's when you know it's probably done. Take out of the oven and leave to cool before turning out - the Agar will set on cooling.
I know flavourings are tricky, make sure they're not oil-based, and ideally water-based. I use alcohol-based ones as the alcohol evaporates (that's what tell myself)
edited 2012: the original recipe uses agar FLAKES. If you have Agar POWDER instead (I finally found some), you need a scant/level teaspoon.
If you don't have Agar then you can use 1TB cornflour - but this makes it NOT suitable for ATTACK.
