Place two thirds of the butter in a pan, add the shrimps and spices and warm through gently for 3-4 mins.
Place this mixture in small ramekins, press down and put them in the fridge to set.
Next, to clarify the rest of the butter, wipe the pan clean and heat the remaining butter gently until you can see the white whey at the bottom of the pan.
Gently spoon out the clear oil and top the shrimp mixture with it.
Allow to cool and set.
This will keep up to 4 weeks in the fridge.
