You must be really old, my mother told me the same history.
God bless your knowledge of history, and your longevity.
When I was a kid Mom gave me a dollar, sent me to the grocery store to buy butter, milk and bread. I came home with change. I’m only 88 till January.
LOL
I am in my mid-60s and can recall my mom telling me the same history about the margarine.
She said it was the scariest thing to look at and never did she want to use anything except butter.
We kids and my father had no problem with margarine. She once said when I can tell the difference between the two I could use margarine. Thought she was being just...well, old-fashioned. Ah, such vanity as a teenager!
Turns out, she was correct. I did eventually learn the taste difference and we only have butter stocked.
When I baked Shortbread the hardest thing to get the others at work to accept that you use ONLY butter when baking a good Shortbread.
Best compliment I ever received was when an older gentleman asked me for the recipe because his mother had come over from Scotland and she swore he had to have had some shipped over. Turns out it was the Shortbread I baked for an office party.
That recipe came from a cookbook older than I am. I value that cookbook.
Rambling on.... food does that, doesn’t it? Bring out the good memories....
