This makes a really quick but impressive looking starter. The pea purée is quite soft, so it doubles up as a sauce. You can make the pea purée before your guests arrive and then the scallops, which are flavoured with only a little cumin and salt, take just minutes to cook
Put the peas, 25g butter and stock in a pan and season well. Simmer for about 3-4 minutes (you want the peas to stay bright green) then put in a food processor or blender with the mint and whizz to a purée. Put back in the pan and keep warm.
Season the scallops with a little cumin and salt. Heat a non-stick frying pan to very hot with a little oil and butter. Sear the scallops for about 1 minute each side (you want a nice caramelised colour on them). Serve 3 scallops per person on a bed of the pea purée with a few leaves dressed with balsamic.
