Grease & line a 20cm x 30cm baking tray.
Place the water & stock cube into a large saucepan & place over a medium-high heat. Bring to the boil, stirring to dissolve the stock cube then lower the heat to low & gradually pour in 250g of polenta, whisking constantly.
Cook the polenta until thick, stirring regularly. This will take around 3-4 minutes.
Next, stir in the butter then once melted, stir in the taleggio & season well with salt & pepper. Pour into the lined baking tray, leave to cool then refrigerate for a minimum of 2 hours but preferably overnight.
Once the polenta has set, remove from the tray & parchment & transfer to a chopping board. Cut the polenta in half lengthways then cut each half into fries roughly 1cm wide - feel free to make them chunkier if you’d prefer.If you’re not planning on cooking the polenta straight away, it will last in the fridge for up to 3 days. Preheat a deep fat fryer (or a saucepan of veg oil) to 180°c.
Whilst the fryer is heating up, coat the fries in the remaining 100g of raw polenta.
Next, fry the polenta in batches for 5-6 minutes or until crispy.
Pile the cooked fries up in a bowl, season with sea salt then grate over a generous amount of parmesan. Serve immediately.
