Tip: I like Coopers Stout because it is a big beer with lots of flavour and bitterness. You could use Guinness if you wanted as that goes great with oysters also. The secret of getting a really good crispy result is to have the batter as cold as possible so make it in a bowl over another bowl filled with ice. Also don’t overwork the batter you don’t need to. Make the batter as thick or thin as you prefer.
