I wouldn’t exactly say ‘hate’, but I really don’t like any goat’s cheese, fennel or dill. Ditto peanuts and peanut butter.
The mere thought of raw fish is repulsive.
I can’t bear cream, or milk unless it’s disguised in something.
Ditto meat fat, unless it’s very crispy streaky bacon.
As for butternut squash, personally I think they’re a PITA to chop/peel, and IMO they’re vastly overrated, taste-wise. But we often get one in our veg box delivery - I microwave it and turn the pulp into a hot and spicy Thai-style soup, which is very tasty.
