Tapenade is a spread made with olives, capers and anchovies, which comes from Provence in the south of France. The olives would normally be too strong for the tuna, so I’ve made a more subtle version with cauliflower and I am not an anchovy fan (but you can add them
in). The tuna gets its delicious flavour from being cured in salt, sugar and spices, which also helps firm up the flesh. In the Vinnies’ kitchen we lightly toast whole coriander and cumin seeds in a pan, then grind them by hand with a pestle and mortar for an extra fragrant finish to the tuna. When making the tapenade I like to cut just the florets (the top of the cauliflower), as this is the sweetest and most delicious part.
