How much is a teacupful?

[soloula]

I've got my Great Aunt Betty's doughnut recipe and just about to make it and it's asking for a teacupful of sour milk. How much is a teacupful? Google seems to throw up lots of different amounts so I'm hoping someone here can keep me right.

However much fit into the teacup that your Great Aunt Betty used when she made her doughnuts, filled up to her definition of 'full' .

I'm guessing maybe around 150 ml, on the assumption that the recipe is quite old and cups used to be small.

I think you're going to have to suck it and see with this one, on the assumption that GAB is no longer around to ask.

Of course, not all great aunts are old or sadly no longer with us. I'm a Great Aunt and I'm under 50, although my great nephews and nieces are not yet old enough to be making doughnuts unsupervised, or consulting MN for help interpreting vague measurements.

It doesn’t really matter, so long as you use the same cup for all your measurements.

But I’m not even an aunt, let alone a great aunt

4 fl oz

I’d say it was one standard cup measure. They are quite small

Actuslly, 8 fl Oz is a US Cup

I’d say it was between 150 mls and 200 mls. So add the sour milk slowly, a little at a time until you get the right consistency, don’t worry if you’ve got some milk left over.

Old fashioned recipes often include instructions to “mix to a soft dough” or something similar, without be very specific about amounts of fluids.
