Dressed Crab Sandwich

A cook dressing a brown crab twists off the claws, cracks them, and picks the white meat out in threads, then pries the body from the shell and scrapes out the soft brown meat from inside. Everything that goes into the dressing is already in the pile on the board. The white is sweet and fibrous and the brown is dark, creamy and faintly bitter, and the whole job of dressing is deciding how the two meet. A fork keeps the white loose, a spoon works the brown smooth, and the shell, scrubbed and emptied, is the dish the finished crab is traditionally served in. The sandwich borrows the same two textures and asks the bread to hold them.

On bread the dressing is short: lemon juice, white pepper, and often a spoonful of mayonnaise to bind the brown meat into something that spreads. Butter goes on first, right to the crust, because crab carries water and an unbuttered slice greys and tears within minutes. One common build spreads the brown meat across the butter like a paste and heaps the white on top, so the sandwich keeps the shell's two zones, smooth underneath and flaky above. The first bite is cold and sharp with lemon, then the white breaks apart sweet on the tongue and the brown follows, rounder and saltier, with a trace of the pepper at the back of the throat.

It is eaten cold and soon after it is made, standing at a harbour wall or on a bench in the wind, and the pleasure is partly the setting. Cromer on the Norfolk coast and Newlyn in Cornwall are among the places where dressed crab is a local trade, and a sandwich there is typically made from meat picked the same day. The bread is soft enough to give at once, so nothing competes with the crab, and the filling is wet enough to slide if the slices are pressed hard. A splinter of shell is the one hazard, a small hard click against the teeth that sends the eater straight to the paper bag to look.

The word dressed does the work in the name. In a kitchen, to dress a crab is to season and arrange it for the table, and the dressing has changed with the century. The seasoning in the earliest printed recipe is oil and vinegar with cayenne, white pepper and salt, which gives a sharp, loose, almost salad-like crab. Mayonnaise replaced it in most kitchens, and the pink Marie Rose sauce now served with restaurant dressed crab is reported to date from the 1960s, around the same time as the ploughman's lunch. On the sandwich the choice shows in how the filling behaves: oil and vinegar soak into the crumb, mayonnaise holds the meat in place and stays put.

Brown crab, Cancer pagurus, is the species behind nearly every dressed crab in Britain, and the fishery behind it is mostly small boats working baited pots close to shore. The best crabs feel heavy for their size, which is how a cook or a fishmonger judges whether the shell holds a lot of meat or a lot of water. A light crab gives a watery, thin-tasting filling, and a sandwich made from it goes limp quickly. A heavy one fills a sandwich with dense white meat and brown that sets almost like a pâté.

To Dress Crab, Recipe 244

Isabella Beeton's Book of Household Management, first issued as a bound volume in 1861 after appearing in monthly parts from 1859, prints the recipe as number 244, "To Dress Crab." The instruction is to empty the shells, mix the meat with two tablespoons of vinegar, one of oil, salt, white pepper and cayenne, and put it back in the large shell, garnished with lemon slices and parsley. It is priced at between tenpence and two shillings and said to be enough for three people, and the cook is advised that a middle-sized crab is best and should feel heavy for its size.

The book lists the dish among its coloured plates, alongside a boiled round of beef, a roast sirloin and a charlotte aux pommes, so dressed crab was an illustrated centrepiece of the Victorian table at the point it first appears in this book. No record names who first put dressed crab between slices of bread.

The same entry fixes the season. Beeton calls dressed crab available all the year but not so good in May, June and July. The 1861 recipe gives the dish a calendar as well as a plate, and the sandwich inherits both.
