I bought this book at a boot sale - it dates from the 70's, but the recipes seem older than that. It is called Farmhouse Fare and looks like one of those books where hundreds of people contribute family recipes. There is a whole section on Pig curing. Fortunately the OCR software on my scanner can read it all in (i'd never have typed it all) so i'll slowly scan in these recipes, and post them here.
If you see any spelling mistakes or something that looks obviously wrong, let me know - OCR software is never perfect. It has particular difficulties with the 1/4 and similar subscripts - substituting them with a ^ or a | or sometimes an 'I'. I've tried to fix these, but if you see any errors, please let me know.
NOTE: These recipes are here for historical reference - the amounts of saltpeter have not been checked for current EU or US health standards.
