Just to let you know, I have posted the recipe for a very low fat (2%) gooseberry fool here http://www.growyourown.info/page165.html
ALTERNATIVE FRUITS FOR LOW FAT FRUIT FOOLS
These can be made using the thickened fruit juices and sieved pulp of plums, damsons, raspberries, tayberries, brambles, blackcurrants, redcurrants, josterberries.
Fools made from plums are particularly good.
