Hi there

Thank you x

For the pastry just add more flour,liquid, if you make too much it's not a great loss, as for the filling can you add more liquid/egg?

Thanks... I'm unsure how much extra to add...maybe add half the ingredients and then get rid of any leftovers? At least then there would be an even amount?

At a rough guess try dividing the ingredient amounts by 9 then multiply by 10
i.e. 27g divided by 9 = 3g x 10= 30g

Thank you. That's what I ended up doing and it was fine!
