Learn Spanish (Latin America): El chile es tan fuerte como para quemar el paladar. - The chili pepper is strong enough to burn your palate.

Yes! While you could use a literal translation like lo suficientemente fuerte para, the structure tan + adjective + como para (literally "so strong as to") is a very natural and common way to express that a threshold has been reached. It means exactly "strong enough to".

Why do we use the infinitive quemar here instead of como para que with the subjunctive?

We use the infinitive because there is no change of subject. The chili pepper (el chile) is both the thing that is strong and the thing doing the burning. If the sentence introduced a new subject (like "strong enough for you to cry"), you would use como para que followed by the subjunctive: tan fuerte como para que llores.

Why does the Spanish sentence use el paladar (the palate) instead of tu paladar if the English translation says "your palate"?

In Spanish, it is a standard rule to use definite articles (el, la, los, las) rather than possessive adjectives (mi, tu, su) when talking about body parts. The English translation uses "your palate" to mean "a person's palate" in a general sense, but Spanish simply uses el paladar.

Is fuerte commonly used for spicy food, or should it be ?
