[Sca-cooks] [OOP] Mrs. Beeton's Sifted Sugar

[Volker Bach]

'Oi, 'Elp!

I'm trying to recreate Apples in Red Jelly from
Isabella Beeton's Book of Household Management,
and she says to use 'sifted sugar'. What does she
mean by that? I would automatically assume
confectioners sugar, except that you're supposed
to stuff it into baked apples which would be a
waste of the powdery stuff. Maybe something like
'fine enough to pass through a sieve', which would
mean caster or granulated?

Thanks
