The original very classy, but somewhat-dated recipe is for lobster Thermidor, but lobster or langoustines (Norway lobster) work very well.

In the original version, the flesh is put back into the shell rather than into ramekins, which is much prettier, but rather tricky to do. If you want to try it, stand the half-shells in a bed of coarse salt to keep them upright.
