What to do with radishes in the heat

Radishes are a cool weather crop, as most gardeners know. I harvested them a while ago, but I left one of the biggest and healthiest to flower. The bees like the flowers, which turn into green pods. The pods (when green) can be eaten, such as in a stir fry. The photo below shows a pod, but it's past the point of eating but not at the point of collecting seeds. As the pods ripen, they get brown and dry. Inside there will be radish seeds. 

I have a problem waiting until the seeds are fully developed--they'll look dark. If you grow a hybrid or several varieties, the seeds may not develop into the exact same kind of radish. But these are some of the easiest seeds to save. The photo below shows how the seeds should look. Happy seed saving!
