I haven’t tried snail caviar. I have no real desire to, either, though now Clarkson’s become an unofficial ambassador, I’m sure they’ll appear on menus soon; more than likely at a press lunch of some description, or at a pop-up. In that case, I hope past reviews ring true: these dainty unborn land mollusks are said to be reminiscent of “baked asparagus” and “mushrooms”, with a “subtle flavour” and “woody notes”. They are mostly deployed as their fishy cousins: on blinis, atop soups, with baked fish and so on.
