UPDATE
Well, it can't have been too bad, because OH ate it without a word, and he's not the kind to keep his thoughts to himself if he didn't like it.
That said, when I then asked if it had tasted ok, and told him what I had done, he said that it didn't taste the same as normal, but that was all he said. I have to agree, it didn't taste exactly like it usually does, but it didn't taste 'odd' or in any way unpleasant either. Just slightly different, because of the pepper.
In fact, I think that the salt might actually have enhanced the flavour, but I will try to stick to my normal recipe next time though
