The next mayonnaise variation is ‘green mayonnaise’, which it recommends adding herbs or spinach. I made a normal mayo with mustard and a fruity olive oil and added finely chopped herbs from the garden. Chives, thyme, and either marjoram or oregano, I can’t tell the difference. John isn’t keen on an overdose of herbs as it is. I wasn’t much impressed either. I suppose a good handful of parsley would have been better. And the mayo was well coloured by the mustard and the dark olive oil as it was.
