No, but I found this:"Both the thymus and pancreas forms of sweetbreads 
must be properly prepared before they can be cooked. Raw sweetbreads 
often have a layer of fat and a sinewy outer membrane which must be 
peeled away first. Many professional chefs recommend soaking the 
sweetbreads in an acidic bath made from water and an acidic liquid such 
as vinegar or wine. The sweetbreads should be soaked in this bath for 
several hours, and the water should be changed out several times. This 
process is said to make the membrane easier to remove and also drain off 
any remaining enzymes and blood. Ideally, sweetbreads should be white or 
slightly pink in color."

I had sweetbreads once many years ago, liked it but never seen it since 
and I no longer eat in restaurants.
Maybe I could order it from a butcher? Would it need be frozen?
