How to Adapt a Recipe for Different Sized Tins?

This table uses the 8” round tin as its base and will help with round and square shapes. For any other shape, fill your 8” round with water to the depth required, then tip that water into the shaped tin and you will be able to compare the quantities and adjust accordingly .

Examples: 12” round/11” square will require the base recipe to be multiplied by 2 ½ for example 200g will be increased to 500g. 4” square/5” round use 1/3 of the base recipe, for example 200g will be reduced to 67g.
