Large White Butterfly Eggs

There have been lots of Large White butterflies around my garden and veggies the last month, especially this last few weeks.
I've been known to shake my finger at them saying 'Don't you even think of laying eggs in my Kale cabbage!'.. knowing full well that they will.
To my surprise and as predicted, here are the eggs but on my radishes :(

I've got no idea what to do about this just yet, and the eggs will hatch in the next few weeks, about the same time this radish is ready to pick and eat..
