Vacuum seal with 2 slices of lemon rind. Sous vide at 49ºC for 45 mins. This temperature gives a meaty texture - medium & juicy, Leave it to rest for 10 mins before continuing.
Step 3: Pan fry or griddle
Heat some oil in you pan & make sure it is very hot before quickly frying your tuna. Tuna drys out VERY fast so be sure not to overcook at this stage.
Serve with my soft polenta recipe.
