There are several gluten free yellow mustard options available in the store. However, I had a recipe that called for 1/8 c. of mustard and I didn’t want to go to the store, buy a thing of mustard, use a tiny bit, and then have it sit around in my fridge forever. Fortunately, I was able to be a kitchen ninja and use my surroundings to whip up some mustard!
Ingredients:
1/8 c. water
2 T. dry ground mustard
1 1/2 T. white vinegar
1/4 tsp cornstarch
1/8 tsp salt
1/16 tsp turmeric
small pinch garlic powder
small pinch paprika
Directions:
Using a very small pan that is NOT aluminum (apparently the vinegar can mess with the aluminum?), whisk all ingredients together. Turn on the heat to medium/medium high and cook until thick- about 5 minutes. Cool and use as a direct replacement for store-bought mustard. I think it made about 1/8 to 1/4 cup mustard.
