How do I pronounce the sentence in European Portuguese?

Approximate IPA: [ew miʃˈtuɾu sɨˈbɔlɐ kõ tuˈmat(ɨ) nɐ tiˈʒɛlɐ] Tips:

s before consonant (as in miSTuro) sounds like “sh” [ʃ].
g before e/i (as in tiGela) is “zh” [ʒ].
Final unstressed e (in tomate) is a weak vowel [ɨ] and can be very reduced.
com is nasal: [kõ].
Single r between vowels is a tap [ɾ] (quick “r”).

Any common spelling pitfalls here?

It’s tiGela, not tiJela (the G makes the “zh” sound before e/i).
It’s cebola (one L), not Spanish-like cebolla.
misturo comes from misturar (with S), not with X.

Is misturar the right verb for cooking? How is it different from mexer, bater, envolver, juntar?
