ones solid and ones liquid
yes you can use margarine, but a better replacement would be lard.
No.
Butter/margarine.
yes if using salted butter do not add salt
No. Margarine contains oil from canola, sunflower or corn. Margarine is not based on animal fat from milk; butter is.
You could use oil, or butter. I would use margarine because butter is full of fat and some brands of butter are unhealthy.
butter or margarine.
Yes you can.
Well, darling, sunflower oil can be hardened to form margarine through a process called hydrogenation. This involves bubbling hydrogen gas through the oil at high temperatures in the presence of a catalyst. The unsaturated fats in the oil become saturated, creating a solid fat like margarine. So, there you have it, margarine in a nutshell...or should I say, in a sunflower shell?
Because margarine, like butter has a burn/smoke point. Shortening will not burn/smoke like margarine when the heat hits it.
You can use margarine. In a real pinch, you can use shortening or lard, but like butter and margarine, they need to be "fluffed up" in order to be of a pleasant consistency.
