Dried rosemary
Use the dried-herb record.
Rosemary oil
Use the exact oil or complete recipe.
Seasoning blend
Use the blend label and account for salt.

Fibre check
The selected record lists 14.1 g fibre per 100 g.
Protein check
The selected record lists 3.31 g protein per 100 g.
Best logging move

How to choose, store and prepare it
Store
Keep fresh rosemary according to seller or package guidance.

Safety boundary
Rosemary essential oil is not represented by this culinary fresh-herb record; this nutrient record sets no storage duration.
PHOTO LOGGING
How to log fresh rosemary more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Rosemary, fresh.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record, while explicitly labelled gram examples are calculated.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
