Welsh Rarebit is a noble version of cheesy toast. Everyone loves cheesy toast! Our Rarebit is a proud thing and, if we might say so, extremely popular. So it is odd that Fergus gleaned this recipe from a chef who had previously worked at Buck’s Club, which was well known at the time for selling the worst rarebit in London. There is another thing that we might add, if you are amused by a little mathematics. At St. JOHN Smithfield we sell an average of forty-five Welsh Rarebits per day. Taking into account annual closures, in this, our twenty-fifth year, we will have sold somewhere in the region of 405,000 rarebits. By the time we are thirty we will have surpassed the half-million mark. Onward!
