Aunty'sAunty's Spotted 2 x 95g

Odd question here, but what are the approximate dimensions of this product? I want it to fit inside a prank gift box. Thanks!

How does the buyer prepare this item? Boil on stovetop in the can? Microwave? Is it already cooked and ready to eat?

is $6.77 for one pudding a lot of money? I'm thinking that's borderline ridiculous.

how many little containers do you get for this price?
