This is an old thread but i hope people arent still freezing everything. I just read CA's post and was shocked at the freezing of ginger, garlic, coriander and tomato puree! Poor veg, what have they ever done to you?
Im sure habits have now changed but i wanted to add a comment for any newbies:
Freezing alters ingredients, it doesnt suspend them in the same state. Anything other than industrial freezers arent freezing the ingredients fully. Apparantly you need to get to about -80c to do that. This is why frozen goods have a shelf life.
Just compare a frozen base sauce to a fresh one - there you have the evidence.
Can people really not get hold of ginger, garlic and tomato puree easily??
Restaurants dont freeze them in portions do they?
You dont need a specific brand of tomato puree, that's crazy talk! A sign of curry-forum-madness. White tower is probably chosen because of the quantity and price. It's the same as supermarket stuff.
Restaurants dont exactly buy good quality ingredients do they? Veg out the boot of a car, preground spices in enormous quantities, precooked atlantic prawns, long life cream, frozen meat, lemon juice in a bottle...
Think about it! That's why a main course can cost under ?4
Anyway, i know telling you to not freeze your base sauce will give you a headache. So if you're happy with your results ignore everything i've said. However if you still think some magic is missing from your curries my tip is to make a big batch of curries at a time, or cook some more the next day or two, as the base can be kept on the stove or in the fridge.
You can then freeze the finished curries (once cooled and then chilled in the fridge) and they will behave themselves better. Frozen base sauce always dissapointed me.
