What uses are there for basil flowers? I have tons of basil in my herb spiral.

However, this stuff is precious, and I always feel bad when I throw away the basil flowers when I make pesto sauce.

Is there a way to use the basil flowers when cooking?
If you pinch off the basil flowers as they start to grow, the plant will produce more leaves. (Yes, this is a horticultural answer, but it will help you make more yummy dishes with the leaves.)
