I made this sauce, and to be honest its green and very unappealing but it tastes ok, and the DS ate it so it must be ok.
Failsafe tomato sauce substitute:
1/2 Leek (The green half)
50g Butter
1 850g tin of pears drained.
100g Brown sugar
2tsp Citric acid
50g Butter

Add all other ingriedients. Mix speed 4-5 10-20 seconds.

Puree by slowly turning up to speed 9 for 30-40 seconds.
