Yummomatic: How to always use same translation for 2 words

Hi, Every recipe imported with Yummomatic uses a different wording for referring to the list of ingredients and the list of instructions. How can I make sure to always use same wording, and most importantly, always use same translation. My site is in Spanish, and the word "ingredients" sometimes is correctly written as "ingredientes" but most of the time it is something very different. Same happens for the word "instructions". Is there a way to have those 2 words always the same output in spanish? Maybe avoiding translation and doing a regex? Thank you.
