My granny Agnes Isabella had a system I never fully understood. She would send me down to Montrose Harbour to buy crab — a small boy dispatched alone to the quayside — and she always knew the boats would be there. Not the same day, not the same time each week. She just knew. What I was walking into, though I didn't know it then, was the last years of the traditional inshore shellfish trade on the Angus coast: wooden creelers working the rocky skerries beyond the South Esk, catch sold straight off the planks before health and safety regulations ended pier-side trading for good. The crab was always fresh, always brown, always a partan — and what Agnes Isabella made with it was partan bree.

Partan is the old Scots word for crab. Bree means juice or liquid broth. This Scottish crab soup is one of the great undiscovered dishes of the Scottish kitchen — rich, delicate and deeply satisfying. I make it at Casa Adora with buey de mar, the Spanish brown crab, which is the closest equivalent to a Scottish partan you will find on this side of the Bay of Biscay.

One buey de mar gives two generous bowls. Eat one tonight, take the other for lunch tomorrow. No freezer required.

Montrose Harbour and the Inshore Fleet

What I experienced in the 1960s was the peak of the traditional small-scale inshore shellfish trade. The boats working out of Montrose were wooden creelers and dual-purpose day-boats, built for the rough conditions at the mouth of the River South Esk. The Angus coastline — rocky skerries, deep underwater gullies — is prime habitat for brown crab and lobster. A significant portion of the catch was sold directly off the planks or straight from the wicker creels on the quayside. A hyper-local economy, before commercial regulations ended it.

Agnes Isabella knew the boats would be in because she knew the men who worked them. That's how it worked.

What You Need for Partan Bree

• 1 buey de mar (Spanish brown crab), cooked — meat removed, white and brown kept separate, claws kept whole
• 45g long-grain rice
• 300ml milk
• 300ml light chicken or fish stock
• 75ml single cream
• ½ tsp fish sauce — in place of anchovy essence
• Salt and white pepper
• Fresh chives, chopped, to finish

How to Make This Scottish Crab Soup

Cook the rice
Simmer the rice in the milk over a low heat, stirring occasionally, until completely soft and beginning to break down — around 20 minutes. Do not drain.

Build the soup
Add the stock and the brown crab meat to the rice and milk. Stir well and simmer gently for 10 minutes.

Blend
Remove from the heat and blend until smooth. Return to the pan over a low heat.

Finish
Stir in the single cream and fish sauce. Taste and season carefully with salt and white pepper — the crab carries its own salinity, so go gently. Add the white claw meat and warm through without boiling.

Serve
Ladle into bowls. Scatter fresh chives over the top. Eat immediately.

Buey de Mar — The Spanish Partan

The brown crab (Cancer pagurus) is the same species whether you buy it in Montrose or Málaga. Buey de mar — literally "ox of the sea" — is what the Spanish call it, a reference to its size and slow movement. The Angus coastline and the Atlantic coast of Spain share similar rocky underwater habitat, which means the crab is broadly comparable in flavour and fat content.

For a partan bree recipe, you want a large, heavy crab with good brown meat — the brown meat is what gives the soup its depth. The white meat goes in at the end, kept in recognisable pieces, for texture and sweetness.

Fish Sauce as Anchovy Essence

Traditional partan bree calls for anchovy essence — a concentrated anchovy extract that adds depth without a pronounced fish flavour. Fish sauce does the same job. Start with half a teaspoon and taste — you want umami, not fishiness.
