Brit-speaking friend:   
"We had pudding after Christmas dinner.   
It was made at the end of September."

Me, totally aghast:  
"September! But, but, doesn't it spoil?!"

BSF, in dignified outrage:  
"No--it matures."

Me:   
"But pudding is made with milk.  
How do you keep it from spoiling?"

BSF:   
"No, no--not that kind of pudding!   
I mean pudding: you know, anything sweet that you eat after a meal."
