I'm gonna make a Halvah Beer, because, why not?
Still in formulation stage, bought a Halvah to eat and mull over the flavors. I'm thinking either brown or porter. Probably roast the seeds a little and mash 'em up. I think perhaps in a hop bag in primary or something to make removal easier.
There is the fat problem..but I've made peanut butter beer before successfully, so I'll work with it. Often times if you're careful you can remove most of the beer out from under the oil, that tends to float. I'd probably remove the bag first, give it another day or so and then go right to secondary. And then after a couple of days into bottles. The second transfer gives me another shot at getting beer out from under the oils and fat.
