Im not sure it’s lactose intolerance in our cases, Monica. I do have a little milk in coffee (though not in tea, it tastes horrible to me) and in sauces, and it doesn’t upset me.
Ages ago now, but my folks once came round the day after we’d had friends round. For the friends I’d made a dip that consisted of about 50% mashed avocado, 50% double cream, and a lot of garlic.
Without thinking, I put it on the table with crisps, etc., for my parents. Only when I saw my father tucking into it with evident gusto did I remember all that double cream!
I told my mother on the quiet - she said, ‘Don’t for goodness’ sake tell him - he’ll be sick!’
He very likely would have, so I didn’t.
