jesus now???
tomorrow?
i think you can ONLY go one way with this:
ingredients, source the very best you can, serve them as simply as possible and they will love you for it
asparagus deffo, in season now with lemon butter and a grind of pepper
halibut? cooked to perfection, served with a homemade mayo and new pots and asparagus and instead do something else for starter (good WILD smoked salmon?, a really good smoked mackerel pate? easy to make)
OR a really tasty hearty stew, my old standby is white bean and chorizo, never gone down badly.
you really must NOT go down the poncey route, it is passe and not what foodies want...they want simplicity and really really good ingredients.
desert british berries (they have arrived) and cream.
