I use a lot of different measurements when cooking from vintage recipes. Getting these right is especially important when baking and can mean the different between a light, fluffy cake and a doorstop.
Below are the weights and measurements that I use. Print this page and keep it handy (the ads and extra stuff won’t print) or you can download pretty versions in pdf format by clicking the images above. Choose from the “books” or “pretty gingham” versions.
