Add all the ingredients in the saucepan.
Use a whisk to quickly whisk all the ingredients together and cook on low heat. Continue to whisk the peanut sauce until all ingredients are well-combined.
As soon as the peanut sauce starts to simmer and bubble, turn off the heat.
Transfer off the heat and top with some ground peanut. The peanut sauce is now ready. You can keep the left over in the fridge for a week without losing the fresh taste.
