If you don’t have time to make the mayo for the tartare sauce ... lemon zest and dill. Stir well to combine – you can use your hands for this, then shape into eight fish cakes.
Mix well and season to taste. Allow 3 crab cakes per person for a starter. Serve the crab cakes on a mound of the celeriac slaw and top with a small dollop of the dill mayo.
