What is it?
The fat-to-lean ratio is the single most important variable in sausage making. Fat provides moisture, flavour, and texture (emulsification). Too lean (less than 20% fat) produces dry, crumbly sausage; too fatty (over 40%) results in greasy, poorly-bound product.
How to use
Enter the weight of your lean meat and fat separately. Adjust the salt percentage (1.5-2% for fresh sausage, up to 2.5% for cured). The calculator shows your fat/lean split, required salt, and an estimated calorie density to help with labelling or portioning.
Example scenario
Classic Italian sausage: 700 g lean pork shoulder + 300 g back fat = 30% fat. Salt at 1.8% = 18 g. Add 50 g ice water for emulsification. Total yield: ~1,068 g of raw sausage at approximately 290 kcal/100g.
Pro tip
Keep all equipment and meat below 4�C during grinding and mixing. Fat begins to smear (fat-cap breakdown) above 12�C, ruining emulsification. For coarse country sausage, 25-30% fat is ideal; for hot dogs / frankfurters, aim for 28-32% with added ice water for a smooth emulsion.
