Every Persian table has a small white bowl on it. People sometimes ignore it for the first ten minutes — too busy with rice, kebab, salad — and then someone takes a spoonful and suddenly that little bowl is the most popular thing on the table.
That bowl is mast-o musir: thick yogurt stirred with rehydrated wild Persian shallots. Cool, garlicky-but-not-really, a little sharp, a little sweet. We serve it with almost everything at the cafe — koobideh, joojeh, lamb chops, even just warm bread. Honestly, if you put a small dish of it in front of me I''ll finish it before the main food arrives.
It''s also one of the easiest things to make in Iranian cooking. Three real ingredients. The only catch — and it''s a real one — is patience. The shallots need a long soak, and the finished dip is twice as good the next day. Make it tonight, eat it tomorrow.
About the shallots — the only thing you can''t fake
The whole dish lives or dies on musir — Persian shallots. These are not the small French shallots you find at the supermarket. They''re a wild Iranian variety, sold dried in little slices, and their flavour sits somewhere between garlic and shallot, but rounder, sweeter, less aggressive. You''ll find them at any Persian or Middle Eastern grocer (ask for "musir" or "dried Persian shallots"), and they keep in the pantry essentially forever.
Could you make this with regular shallots or even garlic? Yes — but be honest with yourself, it''s a different dip. It''s a nice yogurt sauce. It''s not mast-o musir.
What you''ll need
- ½ cup dried Persian shallots (musir)
- 2 cups thick plain yogurt — full-fat Greek yogurt is the closest easy substitute. The lower the water content, the better.
- ½ tsp salt, ¼ tsp black pepper
- Optional but pretty: a small handful of fresh mint, a teaspoon of dried rose petals, a drizzle of good olive oil
How we make it
1. Soak the shallots — really soak them
Put the dried shallots in a bowl, cover with cold water, and leave them for at least 4 hours. Overnight is better. They start out brittle like little white chips and end up soft, almost translucent.
If you forgot — and we''ve all forgotten — pour boiling water over them instead and give them about an hour. Not quite as good, but no one at dinner will know.
If you''re sensitive to strong onion flavour: drain the water, refill with fresh cold water, and soak once or twice more. Each soak takes the edge off.
2. Chop them properly
Drain the shallots and pat them dry. Trim off the little hard stem end on each slice if you see one — it stays tough no matter how long you soak. Then chop the shallots as finely as you have patience for. Fine matters here. Big chunks are unpleasant; tiny pieces disappear into the yogurt and flavour every single bite.
3. Stir, salt, wait
Tip the chopped shallots into a bowl, add the yogurt, salt and pepper, and stir. Taste it. It will taste a bit raw and a bit too sharp right now. Don''t panic. Cover the bowl and put it in the fridge for at least a few hours — ideally overnight. The shallot mellows, the yogurt picks up its flavour, and it becomes the thing you actually want.
4. Dress it up
When you''re ready to serve, scoop it into a small bowl, swirl the top, and finish with whatever you have: a few torn mint leaves, a pinch of dried rose petals, a drizzle of olive oil. Or none of those — the dip doesn''t need decoration to be delicious.
How to eat it
- Next to any kebab — koobideh, joojeh, barg, lamb chops. This is the home base.
- Spooned onto saffron rice or tahdig (yes, on the tahdig — try it once).
- With warm bread and a few olives as a small starter.
- As a dip with crisp vegetables, pita chips, or crackers if you''re feeding a crowd.
- In place of tzatziki in any wrap or sandwich — instantly more interesting.
Notes from our kitchen
- Make a big batch. It keeps in the fridge for a full week and the flavour only deepens. We make it in 2-litre containers at the cafe and run out anyway.
- Don''t freeze it. Yogurt splits, shallots get sad. Just don''t.
- Too garlicky? Stir in a few more spoonfuls of plain yogurt and give it another hour. Problem solved.
- Too watery? Your yogurt wasn''t thick enough. Next time strain it through a coffee filter or fine cloth for an hour first.
If you''re not in the mood to soak shallots overnight, we keep a fresh batch of mast-o musir in the cafe fridge most days — it comes free with every kebab plate. See the menu or order takeout. You bring the bread.
