omg,
when i was working at a VERY high profile restaurant in NYC, the GM asked me why there was dirt in the bottom of his brulee???!!!
They had never used the beans before so it was presumed to be a mistake. Granted this was in the late '80's but geez.
When I make flan and brulee with vanilla beans I try to agitate the custard before pouring into cups, seems to keep the specks suspened but there is always some sinking.
this week it is coconut milk brulee with vanilla, and orange vanilla flan with stoli orange and vanilla caramel.
