Instructions

1. 1

   Dress the brown meat

   Put the brown crabmeat in a bowl. It should smell of the sea, nothing else. If it doesn't, stop here. Add the mayonnaise, a squeeze of lemon, the mustard, and a bare pinch of cayenne. Stir it together gently. You're not making a paste, just bringing the flavours into conversation. Taste it. The brown meat is rich and savoury, almost like a concentrated bisque. The lemon should sharpen it, the mustard give it a quiet nudge. Season with salt if it needs it. It may not.

   Brown meat does the heavy lifting here. It carries all the deep, mineral flavour of the crab. Don't be timid with it. Some people discard the brown meat. Those people are making a mistake.
2. 2

   Check the white meat

   Pick through the white crabmeat with your fingers. Run it through gently, feeling for any small shards of shell. You'll find one or two. That's fine. Better to find them now. Leave the white meat in its natural flakes. Don't chop it, don't mash it, don't mix it into anything. It wants to be itself. A squeeze of lemon juice, a scattering of the snipped chives, and nothing more.

3. 3

   Make the toast

   Toast the bread properly. Not pale and apologetic, but golden and firm enough to hold what's coming. A good sourdough is ideal. Something with a close crumb that won't collapse under the weight of the crab. Butter it while it's still hot, generously, right to the edges. The butter should melt into the surface and vanish.

   The bread matters as much as the crab. If the toast is too thin, it goes soggy. Too thick, and it fights the filling. A centimetre, roughly. Enough to have presence.

   Assemble and serve

   Spread the dressed brown meat across the buttered toast. Not thick, but enough to cover the surface. Pile the white meat on top in loose, generous flakes. It should look like it just arrived, not like it was arranged by someone with tweezers. A few more chives. A lemon wedge on the side. A scattering of watercress if you have it, the peppery bite earns its place. Carry the plate to the table. That's it. That's dinner.

Chef Tips

• •Buy the best crab you can find. A whole dressed crab from a fishmonger is worth the trip. If you can get one that's been picked that morning, so much the better. Smell it before you buy it. It should smell clean and briny, like a rock pool, not like a harbour.
• •Don't throw away the brown meat, and don't treat it as secondary. The brown meat is where the real flavour lives. Rich, mineral, almost umami. Mixed with a touch of mustard and lemon, it becomes the foundation that the sweet white meat sits on. Without it, you're eating something pretty but incomplete.
• •Keep the white meat cold and handle it as little as possible. It should arrive on the toast in loose, natural flakes. The moment you start pressing it or mixing it into things, you lose the texture that makes it worth the money.
• •A glass of something cold and dry alongside. A Muscadet, or a fino sherry if you're feeling that way inclined. The salinity of the wine and the salinity of the crab understand each other.

Advance Preparation

• •The brown meat can be dressed with mayonnaise, lemon, and mustard up to a few hours ahead and kept covered in the fridge. Bring it to cool room temperature before assembling.
• •The white meat is best picked through and checked for shell in advance, then kept cold until you're ready to pile it onto the toast. Do not dress it early. The lemon and chives go on at the last moment.
• •Toast the bread only when you're ready to eat. This is not a dish that waits.
