A dense source of fat and plant protein — useful when appetite is small.
Unhulled sesame paste is high in calcium; hulled tahini has much less.
Contains sesamin and sesamolin, sesame compounds studied for effects on blood fats.
Tahini is one ingredient: sesame seeds, roasted and then ground until the oil comes out and the seeds turn into a loose, pourable paste. Nothing else has to go in. In Iran it's called ardeh, and it's a breakfast food more than a sauce — spooned over bread and mixed with shireh, the thick syrup made from boiled grape or date juice. The pairing has a name of its own: ardeh-o-shireh.
Tahini separates in the jar, with a layer of oil sitting on top. That is normal, not spoilage. Stir it back in before you use it.
The seeds come from a tall summer plant that grows through the heat and dries standing in the field. Each pod holds a row of small flat seeds, and it splits open on its own once the plant is dry enough.
Farmers cut the stalks, stand them in bundles, and shake the seeds out onto cloth. The crop has been handled this way in Iran, Iraq and the wider region for thousands of years, because the pod does the work of releasing the seed.
Everything the finished paste tastes like is already sitting inside that seed. No flavouring is used later.
No oil is added. The mill simply crushes the seeds until the oil inside them comes out and carries the rest into a smooth paste.
That is why a jar separates in the cupboard: the oil floats and the solids sink. It is normal. Stir it back together before using — don't pour the oil away, because it's most of what you paid for.
Keep the jar sealed. Once opened, a cool cupboard is fine. The fridge makes it stiff and hard to stir.
Before grinding, the seeds are roasted. This is the step that decides the taste.
Light roasting gives a pale, mild paste. Longer roasting makes it darker, stronger and slightly bitter. Two jars of ardeh can taste very different for this reason alone, even though both hold only sesame.
If a jar tastes harsh and burnt to you, it isn't spoiled — it was simply roasted dark. Try a paler one next time.
Ardeh-o-shireh is a winter morning in an Iranian home: flat bread, a spoon of sesame paste, a spoon of grape syrup, hot tea beside it. Tahini also thins into the sauce served with falafel and kebab, and sweetens into halva ardeh, the crumbly sesame sweet sold by weight in old bazaars.
Persian medicine reads sesame as warm and moist. Ardeh is treated as a strengthening winter food — something you eat when the weather is cold and the body needs fuel, especially for children, for people recovering from illness, and for anyone doing hard physical work.
The everyday Persian way to eat ardeh is to stir it with honey, or with grape syrup (shireh), and scoop it up with warm bread.
This is winter food. The paste is heavy and oily on its own. The sweetener makes it spreadable and easy to eat. A couple of spoonfuls is a portion — it's rich.
Halva ardeh is sesame paste worked with hot sugar syrup until it sets into a soft block that pulls apart in fine threads.
It is a sweet, not a health food — sugar is a large part of it. Iranians eat it in small slices with tea, which is the honest way to treat it.

Ardeh-o-shireh: stir 1 Tbsp tahini with 1 Tbsp grape or date syrup and spread on warm bread.
Thin 2 Tbsp tahini with water, lemon juice and a little garlic for a pouring sauce.
Stir a spoonful into soup or ash at the end of cooking for body and richness.
Whisk into salad dressing in place of some of the oil.
Stir the jar from the bottom before every use — the oil rises and the paste sets hard underneath.
Sesame is one of the major food allergens. People with sesame allergy must avoid tahini entirely — reactions can be severe.
It is calorie-dense. A tablespoon is a real portion; the jar disappears faster than you expect.
Ardeh-o-shireh is a sweet breakfast. If you watch blood sugar, keep the syrup small and eat it with protein.
Buy tahini with a clear expiry date and keep it cool. The oil goes rancid, and rancid tahini tastes sharply bitter.
Whole and ground sesame can carry salmonella. Choose reputable brands; recalls do happen.
Grape syrup (shireh)
The classic Iranian winter breakfast — sesame paste and boiled grape syrup on bread.
Dates
Blend dates into tahini for a spread that needs no added sugar.
Lemon
Acid loosens tahini and cuts its heaviness; the sauce lightens as you whisk.
Chickpeas
Tahini plus chickpeas is the base of hummus. And makes the protein of a meal.
Honey
A simpler stand-in for shireh when grape syrup isn't in the house.
Eggplant
Roasted eggplant whipped with tahini is a cousin of kashk-e bademjan.
