^ i usually grind my saffron for a bit and then add tiny amount of hot water and keep grinding and then let it sit for a minute with something over the top of the grinding bowl( dunno the proper term) and then pour the mixture right in the rissoto or whatever your making. It makes the saffron flavour 1000x more powerful and this way no saffron will be wasted. ( trust me im persian and we know our way around saffron)
