What it is for
They carry aroma. Most smell molecules dissolve in fat rather than water, which is why you bloom spices in oil. They also conduct heat, shorten gluten and soften texture.
Where it catches you out
Every fat has its own smoke point. Butter burns at 150 °C, extra virgin olive oil holds to 190 — choose the fat for the job, not the bottle.
The knack
Drain olives and remove stones before weighing; do not count brine weight as olive flesh.
Storage and health
How to keep it, and who it suits.
Keeping it
Keep the unopened jar in a cool place for 1 year; after opening, refrigerate in brine for 2 months.
Gluten-free
Plain brined green olives contain no gluten grain.
Glycaemic index
This ingredient carries no meaningful carbohydrate, so it has no glycaemic index. On its own it will not move blood sugar; what you eat alongside it decides that.
