Field notes
The tools are arranged in bake-day order, with separate calculators for tasks such as converting a yeast recipe and tracking dough rise in an aliquot jar. The site says its formulas and worked examples are available to check by hand. It also says calculator entries are stored on the visitor’s device rather than sent to the site.
