First treat from the spring garden...rhubarb crumble

In Britain, the word "tart" has many meanings.But in this instance, it completely and utterly describes my crumble, in fact, it has become accepted practice to view the world thru only one eye for about five minutes after ingestion.You take your first mouthful, including the sugary crust, and you think, "Ooo, that's nice and sweet," and then the tartness of the rhubarb hits you and you involuntarily have to close one eye and then you have to take your second mouthful to balance out the tartness with the sugar and you can't help it...you just keep eating...Wait for it....(Is this becoming a food blog?) :)
