Potatoes

[Manouche]

Been growing potatoes now for three years but today whilst watering noticed something I have never seen befor.
At the very top of the foliage was a small stalk with what looked like two green cherries. Small cherry size and just two on stalks on several plants.
Does anyone know what they are, could only think it could be some sort of seed pod.
The potatoes are Maris Piper.
Thank You x

They're fruit. They're very poisonous, but if you leave them, and grow the seed on, you could well end up with your own variety.
