What is Chocolate Ganache Ratio?

The Chocolate Ganache Ratio calculation tells you your cream needed from a few simple inputs. The figure you are solving for here is the cream needed.

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.
