Cut young corns diagonally in half and slice the onion thinly.

Cut bacon into 2cm wide strips.

Heat butter in a pan, add bacon, young corn, and onion. Stir-fry on medium heat until softened. Season with salt and pepper, then transfer to a heatproof dish.

In a microwave-safe bowl, mix cream corn and flour thoroughly. Add remaining sauce ingredients and mix. Cover loosely with plastic wrap and microwave at 600W for 2 minutes. Stir, then microwave uncovered for another minute.
