I know they make coconut butter... never had.
Margarine (french word) butter made with vegetal oil. It's very popular in Europe !
I tried Fababutter and it is surprisingly good, you don't feel the taste of chickpeas
In Spain we have a product similar to regular butter which is made with vegetal oil (olive, sunflower or other like palm etc that are worse). It tastes "softer" than original butter and is easier to spread even when it is kept in the refrigerator. So yes, of course I could switch.
No, I would never give up my butter
