12. I'd need to use a dairy-free butter

I have seen vegan spreads in my local supermarkets, but they are made from oatmilk - which negates the purpose of doing this because oats are off limits to her. I COULD check one of the stores where the right-wing hippies buy their groceries - there are two of them in my area, Pilgrim's Foods and Natural Market - but I don't like going into either of those places because I don't support homeopathy and both those stores have extensive selections of magical water.
