Ingredients
3 tablespoons mustard powder
3 tablespoons cold water
Directions
Measure the mustard powder into a small bowl.
Add the cold water to the mustard powder, stirring constantly until you reach a smooth, lump-free consistency.
Let the mixture rest at room temperature for 10 minutes to allow the heat and flavor to fully develop.
Stir again briefly and transfer to a serving dish or storage container. Use immediately or refrigerate for up to two weeks.
Comments
This recipe is a genuine workhorse for a Charlotte kitchen—mustard powder is stocked at every major chain (Harris Teeter, Food Lion, Publix, Walmart, ALDI, Kroger), and the total cost is under $1 for three servings. The 15-minute time is honest; you're mixing powder and water, nothing more. It reheats perfectly and keeps for weeks in the fridge, making it ideal for weeknight meal prep or a quick condiment fix. The only reason it's not a 5.0 is that three servings for a condiment is an odd yield—most households will want to scale it up immediately, and the recipe itself offers no flavor variation or guidance on heat level, leaving new cooks guessing about proportions.
