You can't so much tell, but that's smeared blood on the sleeve of my nice cashmere sweater! I was making a cooking video with Daniel Boulud (chicken wings) and he whacked a wing and blood spurted all over my sleeve. Then he felt terrible and tried to wipe it off, smearing it down my arm. Of course, it was my fault. I should have worn a t-shirt or a chef's jacket. But I was trying to preserve a casual feel in the kitchen. There's a reason chefs don't cook in cashmere sweaters.
