Hmm. I've got a spice grinder. That will turn them to powder.I suppose I could just add a spot of water and it will be a paste. Or even mix the powdered seeds into the flour before making the dough. What are the other ingredients in your paste?It's a very fine paste. your only problem is where to purchase it from. I bought it over the internet... unless you have something that is capable of making a very fine paste out of your existing black sesame seeds?
