Why this site exists
Search for a cooking number and you land on a recipe blog: nine hundred words about a grandmother, three affiliate links, an email popup, and then — somewhere near the bottom — a static chart that assumes your kitchen is 76°F and that you are serving exactly one dish.
Each of these tools exists because the honest answer to the question is not a number. It is a rescaled recipe, a converted list, a schedule, or a shopping list. A schedule has your clock times in it. A conversion has your tin and your ingredients in it. None of them can be printed once in a blog post and be right for everybody, which is precisely why they were worth building.
Every assumption is visible and editable, the method is written out on each page, and the limitations are printed next to the result rather than left out. We do not sell flour, starters, tins, scales, courses, groceries or catering, and we take no commission on anything you buy.
What they are honest about
The pan converter refuses to compare tins by diameter, because a 9-inch round holds 27% more than an 8-inch and treating that as “one inch” is how cakes end up on the oven floor. The weight converter gives every ingredient its own density rather than one factor, because a cup of honey is four times the weight of a cup of cocoa. The sourdough scheduler shows windows rather than exact times, because fermentation is a biological process and a schedule printed to the minute invites you to trust the clock over the dough. The party planner treats its cost estimate as an estimate — grocery prices go stale faster than anything else on this site, and the quantities are the part worth trusting.
