  • Create new recipes easily from scratch
  • Adjust the hydration to suit your flour
  • Experiment with different flour combinations
  • Scale the recipe easily
  • Saves you time and calculates recipes quickly
  • Take notes and save recipes for future reference

To create your sourdough recipe enter the desired dough weight followed by the target hydration, the amount of salt and the amount of starter you’d like to use. The weight of the ingredients in grams will be given for you to follow.

If your dough is a little too wet or too dry you can easily adjust the percentage of hydration and the calculator will adjust the other ingredients to maintain the same target dough weight.

You have the option to add different types of flour. For example, you could substitute 10% of bread flour for wholewheat and continue to tweak the recipe until you find the right balance.

Once you’ve fine-tuned your recipe you can easily scale it by changing the target dough weight and the weights of the ingredients will be automatically adjusted.

I used to calculate all of my recipes for my YouTube channel by writing them out by hand and using a calculator. This has saved me countless hours.

And it gets better, the calculator is an ongoing project. The calculator will be continuously developed to improve its functionality while keeping it user-friendly and practical. I hope you will download the calculator and contribute ideas (if you’d like to get involved) to develop the calculator further.

An important word on privacy. I take my online privacy seriously and give your information the same level of care. I will only share my baking content with you and will never share or give any other person or business access to your email address.
