It looks pretty if you still evenly distribute whole bean seeds around the finished puree. The olive oil used should be of excellent quality. If you wish, you can serve it with toasted bread.
Cook the potatoes for 30 minutes. Drain, peel while still hot and press through a potato ricer. Peel the broad beans, if necessary. Cover with water, bubble and soften for 10 min – older bean seeds need longer. Grind in a hand blender.
Mix mashed beans and potatoes in a saucepan. Stir in the butter and gradually add the milk, stirring constantly to prevent lumps from forming. Season the mash with salt and season with pepper and stir over medium heat for about 10 min. Arrange in six portions on a heated platter.
Using the back of a spoon, press an indentation into the top of each unit and drizzle in the oil. Serve immediately.
