Miso butter – Mix butter and miso together in a small bowl until combined.
Golden bacon – Put bacon in an unheated large non stick pan, no oil. Turn the stove onto medium high heat – as it heats up, the fat will start to melt so the bacon cooks in its own fat. Cook for 3 to 4 minutes until golden, then use a slotted spoon to transfer onto a paper towel lined plate. Reserve bacon fat in the pan.
Cook corn – Top up with butter if you don’t have 1 tbsp fat left in pan. Still on medium high, add corn, then stir only every minute or so (this lets it get some nice golden spots), for about 5 minutes until corn is just cooked and is sweet. Add garlic, stir for another 30 seconds. Add sake, stir until evaporated (~15 seconds).
Melt miso butter – Turn off stove. Add miso butter, stir until melted. Add pepper, bacon and green onion, toss until coated with sauce. Serve!
Serve as a side dish. In a corn taco with a fried egg and avocado
