Seriously, now... thank you, Jackie and everyone else. The recipe seems to be a real one from Australia, and there are indeed a couple more ingredients. Find it here.

I realise that for one thing, the actual measurement units are missing, as you'd expect the recipe to specify that "600" are 600 grams of whatever, and you'd expect a volume unit to accompany the liquids and perhaps some of the other ingredients (the "libraries" , for instance, might be measured in volume or in weight).

But "ea" is weird. I do agree it may be a mistake, or maybe there is a sort of template that puts this into the recipes that come into this website when other information (such as measurement units) is missing. In any case, it seems obvious that you cannot use "ea" to talk about 1 sprig of parsley or a jar of stock that you're pouring into your pot.
