1/4 cup water
4 Tbsp dry ground mustard
3 Tbsp white distilled vinegar
1/2 tsp flour
1/4 tsp plus 1/8 tsp kosher salt
1/8 tsp turmeric
Pinch garlic powder
Pinch paprika
Directions
Place water, mustard, vinegar, flour, salt, turmeric, garlic powder, and paprika in a small saucepan over medium heat and whisk until smooth.
