It is better to use animal butter, natural, do not only taste good, but also increase the aroma effect.

Plant-based is much worse, said only plant-based butter is not fat that pure nonsense.

But the solidifying point of vegetable butter is not the same as that of animal. Vegetable butter belongs to hydrogenated vegetable oil, artificial hydrogenation, will be formed in the oil "trans fatty acids", this material long-term consumption will cause cancer. So it's best not to use vegetable butter.
