Food safety and nutrition

Pinchwise does the arithmetic of scaling a recipe. It can't taste, see or smell your food, so please use your own judgment and check the results before you cook.

Amounts are rounded

Scaled amounts are rounded to practical kitchen measures, usually within 5% of the exact value (within 2% for baking soda, baking powder, yeast and curing salt). Words like “about”, “scant” and “heaping” mark bigger roundings. Turn on “Show original amounts” to compare with the recipe as written.

Times and temperatures are never changed

Bigger batches often need longer to cook and smaller ones less time. Use visual cues and a food thermometer. Common safe minimum internal temperatures from FoodSafety.gov:

• Poultry, and leftovers or casseroles: 165 °F (74 °C)
• Ground meats: 160 °F (71 °C)
• Beef, pork, veal and lamb steaks, chops and roasts: 145 °F (63 °C), then rest 3 minutes
• Fish and shellfish: 145 °F (63 °C)

Home canning and preserving

Tested canning recipes depend on exact proportions and jar sizes for safety. Don't scale them. Make the recipe as written, or make separate full batches. See the National Center for Home Food Preservation.

Curing salt

Curing salts (such as Prague Powder or pink curing salt) must stay in exact proportion to the meat. Weigh them on an accurate scale.

Allergies and special diets

The app doesn't identify allergens or check whether a recipe suits a diet. Read ingredient labels, and follow advice from your doctor or dietitian.

Nutrition information

When nutrition information is shown, it is an estimate based on typical values for each ingredient. Real values depend on brands, sizes and how food is prepared. It isn't medical advice and shouldn't be used for medical decisions such as insulin dosing.
