The good news is that the ducks are not roasted IN sulfur. The bad news - they are fed it! -_- But there's more good news :)
Ducks have the ability to metabolize (safely - for them and us) what are toxic substances when consumed by humans.
Aside from their toxicity, lol, sulfur actually has an abundance of medicinal/'well-being' properties highly valued in eastern medicine, When the ducks digest sulfur mixed in w/ their feed, they neutralize the sulfur's toxic elements leaving only the beneficial nutrients for their consumers to enjoy.
With the ducks acting as our middlemen, sulfur's health benefits are also far more potent than your average cures for the common cold or stomach ache. Sulfur (when neutralized) is great for improving blood circulation, anemia, lowering high blood pressure, regulating blood sugar, etc. etc.
Just thought I'd share this tidbit!
Thanks you so much for that lesson!
I *almost* want to run out and eat some now!
I love it when readers educate me on what I think is insanity at its best. :o)
