I have used Cinnamon sticks many times and as it is supplied in relatively uniform amounts, it is easy to portion for example 1" piece of Cinnamon stick.
However, Cassia Bark is not supplied in uniform amounts. The bag I have in my store cupboard contains pieces that vary dramatically in shape and size.
If a recipe asks for a 1" inch piece of Cassia Bark, how can I reliably portion this?
My mindset has me thinking that I should simply use enough bark to form a 1" Squared piece of bark. Reliable, yes, but is this correct?
