From The Anti-Union, February 23, 1799.
The Anti-Union was an Irish newspaper published from December 1798 – March 0f 1799 and was hysterically, viciously, relentlessly against the proposed union with Britain. Here a dinner party with many of the main Unionists is described – you need more context than I have to get the whole joke, but the “hidden” names and tone are plenty funny enough.
Syllabub is a very sweet whipped milk dish. Bubble and squeak is made from the vegetables remaining after a roast dinner.
