Gave this a try last night. Used the Safron base and followed the recipe exactly apart from using reclaimed oil. Just used regular veg oil. I also used precooked chicken.

Absolutely superb. My girlfriend said it was 'restaurant quality'. This is now a definite keeper.
Notes to self for next time:
1. Add tomatoes later as they basically disappeared!
2. Don't use precooked chicken
Cheers!
