Oregano
Flavour Profile
Bold, peppery, and slightly bitter. It has a warming, camphor-like quality that cuts through heavy fats. It is the definitive 'savoury' herb.
Health Benefits
Mainly used for flavour, which it has by the bucketload. It has some useful plant compounds that protect your cells, and a bit of vitamin K, which your body uses for blood clotting and healthy bones.
Buying Tips
Fresh oregano should look vibrant and bouncy, not wilty or blackening at the edges.
If buying dried, look for the 'Mediterranean' label for a classic pizza-shop scent. 'Mexican' oregano is actually a different plant with a more citrus-forward, liquorice punch. Know which one your recipe needs.
Storage
Keep fresh bunches in the fridge, wrapped loosely in a damp paper towel inside a bag.
Store dried oregano in a cool, dark cupboard. If it doesn't smell like anything when you rub it between your fingers, it's dead. Toss it and buy a new jar.
Cooking Uses
Dried oregano is a rare beast that is often better than the fresh stuff. It stands up to long simmer times in tomato sauces and stews.
Fresh oregano is potent; add it towards the end of cooking to keep the top notes bright. It’s the backbone of a proper Greek salad or a tray of roasted potatoes.
Forkin' Food Theory
Oregano is one of the few herbs that actually improves when dried.
Most herbs lose their essential oils when the water leaves, but oregano’s oils are incredibly stable. Drying it concentrates the phenols, specifically carvacrol, which is why dried oregano tastes punchier and more 'pizza-like' than fresh leaves.
If a recipe calls for dried, don't assume fresh is an upgrade. It’s a different tool for a different job.
