DD's pretty much summed it up
white tower is best, but taste wise its very similar to a good quality tom puree out of tube.
i cooked 4 off madras sauces last night and found there was no significant difference using the white tower.
just tasting it out the jar then it does taste a lot better than the supermarket own brand jars. tastes a lot sweeter.
i think if u have it to hand then fine - if not i'm not going to miss it. The extra messing to deal with the bigger container is also a drag (I ended up putting into jars covered with oil ? not keen on freezing unless no other option).
