Butter vs olive oil
Butter spread on a slice of bread (10 g) has about 72 kcal, a tablespoon of olive oil about 120. Per usual portion, butter is 48 kcal lower.
The difference
48 kcal
Both are almost pure fat. Olive oil is all fat, butter has a little water in it, so gram for gram oil comes out a bit higher.
The portions here differ: a thin scrape of butter against a full 15 ml tablespoon of oil. A glug from the bottle is often more than one tablespoon.
Use what suits the dish. Measuring the oil once is the easiest way to see how much goes in the pan.
