it depends what the oil is being used for.
For most cookies you can't use oil in place of shortening.
Yes, melted shortening can replace vegetable oil in zucchini bread, although shortening is not a healthy choice.
No you cant
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.
No. Lard is animal fat and shortening is vegetable oil that has been hydrogenated.
yes
shortening can be used for cookies because you don't have to put it in the freezer like butter. but you can use butter or vegetable oil to replace shortening but you will have to wait.
In cakes: Increase the amount called for by 15% and use vegetable shortening or non-dairy margarine.
Vegetable oil and butter are two types of shortening. All fats and oils are shortening, and can be substituted for each other, but this will affect the flavour and texture of the food, as some shortenings have stronger and different flavours, and also have different melting points.
You have to use some kind of oil. Olive oil is probably the best, although any kind of vegetable or fruit or nut oil will do. The oil combines with the yolk of the egg to form an emulsification. Without the oil, you can't get mayonnaise.
Um.. yeah I think soI've done it before it I think
Yes, but the results might not be the same. Liquid oil and solid shortening have slightly different properties. You might need to use slightly less oil for similar results, when "creaming" shortening the results do not work for oil, but this step would be dispensed with when using oil. Butter or lard, which shortening was designed to replace, will get the same results as shortening.
