Hello everyone, new member here.
My sister asked me this today - real-life physics at work!
She's making Christmas pud & the instructions say it takes 8 hours to cook. However, her bowls are too small, so she's made two little ones instead, and she asked how long to allow to cook them (you're not meant to disturb/ examine them while they're cooking). I guessed six hours.
I don't need any complicated formulae, just the ratio of cooking times; is it proportional to the volume, or the surface area? I have a degree in pure maths , but was always rubbish at physics. I remember there are different types of heat transfer, but please just keep it simple. You can pretend the puds are spherical.
Thanks
