yes.
Yes, you can melt shortening and use in a cake recipe. It will change the texture and possibly add heaviness to the cake, but it will still be good.
Absolutely. I actually use vegetable oil instead of sunflower oil regularly. It makes the cake rise better and taste better too. Vegetable oil is a great substitute for many cooking oils. And canola oil works fairly well too for cakes and most baking. I dont hardly ever use Sunflower oil because it seems to leave behind a taste. And I don't really like it. But as I said, vegetable oil is a perfect substitute.
Olive oil is a vegetable oil. You can often substitute other vegetable oils, but only experience, or a knowledgeable person can tell you it that will work for a particular recipe.
Yes. Margarine is basically solidified vegetable oil, so you should be able to substitute it in a cookie recipe without a problem.
I always use butter. You may want to adjust the salt in the recipe if not using unsalted butter.
yes u can i do it all the time http://recipes.howstuffworks.com/low-fat-baking1.htm
Yes, we can substitute buttermilk for milk in recipe.
The following link is a great samosa recipe; to make it vegan, substitute vegetable oil for ghee. (I suggest canola oil)
I think shortening would be good. Only if its for your lips.
No, they have almost nothing in common. You can use many different vegetable oils instead of corn oil, sunflower oil for example. If you don't have light corn syrup, substitute 1 cup granulated sugar and 1/4 cup water. If a recipe calls for dark corn syrup, use 1 cup packed brown sugar and 1/4 cup water.
Anise oil is what's called an "essential oil" that is typically recovered by steam distillation from a spice, is highly flavored, and costs several bucks an ounce, while "vegetable oil" usually refers to oils that are cold-pressed from oily but mostly bland seeds (cottonseed, rapeseed, sunflower seeds, corn) and are much less expensive. If you're asking if it's vegetarian/vegan ... yes. If you're asking if you can substitute it for vegetable oil in a recipe, I wouldn't.
It is a blender recipe: apple, licorice, sunflower seeds I swear it is
