A household member, who shall remain nameless, helped me prepare a large batch of chicken according to the following recipe by making the marinade and putting it over the chicken to marinade. However, they forgot the mustard. I now have about five lbs of raw, chicken thighs marinated in said mustard-less recipe, and as I see it, a few options: 1) put it in the oven as is - it will taste different but maybe still good/edible; 2) drizzle mustard over it (the suggestion of the helpful-but-absent-minded household member); or 3) make a new marinade and marinate the chicken a second time.
Here is the recipe: https://paleoleap.com/mustard-balsamic-baked-chicken/.
I would love suggestions and thoughts. Thanks!
