I don't think I've ever heard of anyone making a pulled noodle with cuttlefish ink, but it worked nicely. Bread flour, one egg, two small packets of cuttlefish ink and water to make a stiff dough. Kneaded half an hour or so, rolled out, oiled and cut into thick strips, rested for 5 hours. Then pulled and as you can see stuck to the counter top on the ends so they didn't spring back. Normally I throw them right in the water, but I wanted to dry these. I think they're stunning.
So how to cook them? I think in a roasting pan, they're about 6 feet long! Then maybe serve in dashi stock with mentaiko. We'll see.
