Dear Eliana,
Here in the UK I would use �consist of �; and in certain situations, �consist in �.
Oxford English Dictionary
CONSIST: verb, no object.
1) (consist of) be composed of or made up of: the crew consists of five men.
� (consist in) have as an essential feature: his poetry consists in the use of creative language.
2) (consist with) archaic be consistent with: the information perfectly consists with our friend �s account.
I don �t think that I have ever heard an educated person use �consist on �.
I hope that this helps you.
Por favor, �podr�as darme una buena taza de caf� tambi�n?
