I LOVE chilli beans on nacho chips. But alas, soy sour cream is blarrrghhh... not appealing to me.
I invented this last night:
Vegan Sour Cream
Juice of 1 lemon
1/4 cup of coconut cream
Stick in the blender and whizz until creamy.
Delicious. Ever so delicately flavoured like coconut. Even nicer when you add chopped cucumber on the side to offset the spicyness of the chilli beans.
