Very interesting conference idea; I'm sorry I can't attend
I see that the press release mentions Delmonico's, which I believe, was opened as the grander heir to an earlier ice cream restaurant. Delmonico's one-time chef, 
Alexander Filippini gave a recipe for "Greater New York Ice Cream in his magnum opus, 
The International Cookbook (1906). It appears as a suggestion for Thanksgiving Evening Dinner (
for the full day's menus, and descriptions of the dishes, see this thread):
 The dinner lineup:

Greater New York Ice CreamMy summary of the recipe:
Greater New York Ice Cream appears to be a sort of ice cream bombe: almond ice cream lines a mold, then a layer of raspberries is laid down. A mixture of whipped cream and custard with marrons, vanilla, and curacao or benedictine is added next to the mold, then layers of raspberries and almond ice cream top it off. I love the  suggested garnish: pieces of angelica cut to form the letters G.N.Y., a piped border of candied cherries and whipped cream, and a sprinkle of chopped pistachios. (Mon Dieu!)[/quote]
I wonder if Mr. Weir is planning to serve G.N.Y. Ice Cream to his audience. I certainly hope so!
Being British, I'm sure that Mr. Weir intends to discuss the history of ice cream in London. For those who are passionate about the topic, in London, the 
Canal Museum is located at the ice house of Carlo Gatti, Swiss originator of the ice house and ice trade in London, and the man who made ice cream available to the masses in 19th century England.
                    
                        
                            
Man :  I can't understand how a poet like you can eat that stuff.
