Is the word ingredientes the same in Brazilian and European Portuguese?

Yes

The word "ingredientes" is spelled identically and carries the same meaning in both Brazilian and Continental Portuguese. The only difference is the pronunciation. In Brazilian Portuguese, the vowels are generally more open, and the syllable-timed rhythm makes the word sound more melodic. In Continental Portuguese, the rhythm is more stress-timed, and unstressed vowels—particularly the final "e"—are often reduced or almost entirely silent, making the word sound more clipped.

Brazilian Portuguese Examples:

1. Eu preciso comprar os ingredientes para o bolo. (I need to buy the ingredients for the cake.)
2. Quais são os ingredientes desta receita? (What are the ingredients of this recipe?)
3. Esqueci de anotar um dos ingredientes. (I forgot to write down one of the ingredients.)
4. Os ingredientes estão todos frescos. (The ingredients are all fresh.)
5. Você tem todos os ingredientes necessários? (Do you have all the necessary ingredients?)

Continental Portuguese Examples:

1. Eu preciso de comprar os ingredientes para o bolo. (I need to buy the ingredients for the cake.)
2. Quais são os ingredientes desta receita? (What are the ingredients of this recipe?)
3. Esqueci-me de anotar um dos ingredientes. (I forgot to write down one of the ingredients.)
4. Os ingredientes estão frescos. (The ingredients are fresh.)
5. Tens todos os ingredientes necessários? (Do you have all the necessary ingredients?)
