Really, people...how fussy can you get about eggs (angels dancing on the head of a pin)? Eggs can usually be purchased in only a couple of structured volumes...12 eggs, or possibly 6 eggs. Is this ingredient rangling for the shopping list? If you have "some" eggs, you may need to buy more for a specific, like lemon curd (both whole eggs and yolks). If one has doubts, wouldn't one at least check one's own *recipe*, in the book that one owns, rather than just going by the indexed ingredients?
I use the ingredients list to check if I have all the stuff. THEN, I go to my book (which is why EYB has just lists of things, and not the actual recipes) and make sure I don't need more eggs [having just checked and seeing that I only have 4 whole eggs in the fridge].
Common sense may be victim of over-zealous member indexers. Please don't scare off other volunteers from attempting indexing by arguing to death how many eggs....well, dance on the head of a pin.
