homemade azuki bean paste for anman

Maki-san, I tried to make some azuki bean paste-filled buns the other day, and while the steamed bread turned out great, the azuki bean paste was...just okay. I followed a recipe I found online. I was wondering if you had a recipe for the paste? I would buy it pre-made, but I had a hard time finding azuki beans in my town, let alone premade azuki bean paste. Help? Onegai shimasu! Kyandasu
