60g of oil is 540 kcal-ish. The chili pepper is comparatively calorie free, so yea, 440kcal makes total sense.

Is it the tsp that's throwing you off? I think there's a typo - 4 tbsp would be about 60g. 4tsp I would expect to be about 20g.

I way prefer dealing in mass for cooking and baking personally...
