Risotto with Saffron, Parmesan, and Wine

I make risotto quite often, but the time has come to prepare one of the more sophisticated versions, namely with saffron. I received a small bag of saffron, thinking it was so intense that it would be enough for 5 dishes. Unfortunately, the entire bag went into one risotto.
The color turned out nice in the end, the taste was great, especially with parmesan, wine, thyme, and (surprise) cornflower petals. However, it was a bit less efficient than I expected. I will try again once, as I am not sure if it's a matter of the saffron or just my imagination 馃檪
