Can I substitute yellow mustard seeds for black mustard seeds?

I just tasted a yellow mustard seed and a black mustaard seed. The yellow is milder and sweeter than the black, which I've used to make mustard. Overall, I would stick to the yellow seed.

Black mustard seeds are stronger than yellow, so you may want to increase the amount of yellow when you substitute

Depending on where you live black mustard seeds can be kind of hard to find. There is a subtle difference in flavor but if you need to substitute go ahead.

You probably shouldn't, but we won't tell!
