I just finished making a bar recipe that has the usual crumb topping/crust pressed in the pan. I wish that cookbook authors would give the yield in recipes like this. It's fine to tell me to reserve half of the mixture for the topping - but how about saying that you expect it would yield about 4 cups, and so reserve half (2 cups) for the top?
Another problematic item in recipes is sweet potatoes. I hate it when the recipe says to use one sweet potatoe. If you want to make a substitution, it's impossible because you don't have an actual measurement, such as 1 cup or 2 cups, etc.
I find the same problem with berries sometimes - I don't want to have a pint of blueberries as the ingredient; I want to know if I should have one cup or 1-1/2 cups, etc.
Has anybody else run into issues like this and know of any authors who provide this additional info on a regular basis?
This is one of the things I'm going to start looking at when I decide whether to buy a cookbook or not.
