Don't have mustard powder. Can I put actual wet mustard in my mayonnaise?

[shockthemonkey]

Making my mayonnaise from scratch, and St Delia recommends adding mustard powder. But, the cupboard is bare and the shop most likely to stock it is awaiting a delivery.

So, can I make the mayonnaise as usual and then just stir in the mustard at the end?

Yes!

No, St Delia will appear and smite you 😄

Yes, do it.

Of course 🤩

Yes, mustard powder is a thing from my distant childhood.

We like wholegrain mustard in our coleslaw too.

Thank you everyone! I shall do so and try to dodge the smitings from the cooking saints 😇

I add all sorts of things to mayo.
Various made mustards, horseradish, sriracha, miso, pesto.
Not all at once, but there's a thought......

Yes you can, I always use dry mustard powder when making mayonnaise but that's because I usually have it, if I was out of it I'd just use the jar stuff.
