Questions & Answers about Se o molho ficar azedo, minha avó tira as sementes do tomate e começa de novo.
Here, ficar is most naturally understood as the future subjunctive.
In Portuguese, after se meaning if, when you are talking about a possible future situation, Portuguese often uses the future subjunctive:
- Se eu for... = If I go...
- Se ele tiver... = If he has...
- Se o molho ficar azedo... = If the sauce turns sour...
With many -ar verbs, the future subjunctive form looks exactly like the infinitive, so ficar can look confusing. But in this sentence, it is functioning as future subjunctive, not as a plain infinitive.
