Monkfish

Soak gelatin in a bowl of cold water until softened, about 5 minutes.

Peel the onions and carrot and thinly slice both.

Combine fish stock and half of the white wine with the onions, carrot, bay leaf and mustard seeds in a pot and bring to a boil. Reduce heat to low and let steep for 15 minutes.

Add softened gelatin to hot stock and stir to dissolve (do not let boil).

Stir vinegar into stock, remove from heat and let cool slightly. Season with salt.

Pass stock through a sieve into a bowl. Remove bay leaf and reserve vegetables.

Rinse monkfish, pat dry and cut into bite-sized pieces. Season with salt and pepper.

Heat remaining white wine in a small pot over medium heat. Add monkfish and gently simmer until opaque throughout, about 5 minutes.

Rinse dill, shake dry, pluck fronds and finely chop. Add to strained stock.

Arrange reserved vegetables and the fish cubes decoratively in 4 soup plates.
