Nigella (love-in-the-mist) seeds in bread

If I am early at Kings Cross I take a detour to St Pancras before walking to my osteopath in Caledonian Road. There is a stall which sells lovely bread. This morning I got one with potato flour which also had nigella (love-in-the-mist) seeds in it. If you can have poppy seeds in bread and cakes, why not nigella?

I usually have masses of love-in-the-mist but this year, perhaps due to the long winter, I don't have much in the garden at all, so won't have spare to try in a loaf. Not too disappointed, as I can't taste the seeds in the bread so would only be using them as seeds are good nutritionally.
