PHOTO LOGGING
How to log marshmallows more accurately

Match the exact reference state: Candies, marshmallows.
- 02
Use edible grams. Every named weight is held by the selected local USDA record. The 100 g entry is the source nutrient basis; no household portion was invented.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
