Nuts and seeds

Yesterday I tried raw unsalted pistachio nuts and loved them a lot! I know only one place in Moscow where they are sold, and not that cheap (165 RUR per 0.5 kg, 1 EUR ~ 43.5 RUR). We ate the 300 gr too quickly =)
Something is wrong with the white sesame I bought. I put it to soak, but today it smells bad and doesn't start to germinate after enough time for this.
After I started to soak all seeds I don't like them dry anymore. They change their taste after the crucial moment of waking up due to water.
