I'm not sure to understand your question but the way I see it there shoud not be problem in using the word "application" or similar. Cheers.

I usually read different recipes because I love cooking, and more often than not I came across with the word "instructions" as a synonym for "recipe". It gives the idea o following several steps. I feel that in your example it might function correctly.

In this case, a "culinary creation".
Creation: something new that is made or produced : something that has been created (in this case, food dishes).

In the light of Nicholas' scathing disagree, here are some of my reasons for not using "application", although it could work at a pinch.
1.- Asker seems reluctant to use the literal translation.
2.- Asker mentioned "creating gels".
3.- Several published texts mention the term "culinary creations"... And it sounds pretentious enough to go hand-in-hand with fancy-dancy recipes using foam and gels and CO2... etc.
I rest my case.
PS: I'm not really sure what NB means by a stylised marketing term, or why it wouldn't be suitable for an informative video.

NB: James's suggestion of "technique/s" is closer in the meaning of 'aplicación' as used in the source text. Although I stand by my original suggestion, even though it is a bit of a get-out.

Hello, I'm not sure why there is no option to respond in depth to Neilmac, but I want to clarify a few things, because the answers that are getting voted up are patently incorrect. "Application" or perhaps "culinary use" are by far the most correct terms. First of all, I don't think my disagreement was "scathing" or personal in any way; however, since he's chosen to attempt to correct me, I feel the need to point out that none of Neilmac's counterarguments are correct or even necessarily relevant to the question. First, I note that the linguee page he links doesn't contain a single example of culinary creation being translated as "aplicación"... Then he says:
1)"Asker seems reluctant to use the literal translation." - How do you know? The asker doesn't say that. And even if they did, it doesn't matter because in this case the literal translation is the most accurate given the meaning of the source text and the usage of the term in English-language texts about gastronomy and cooking.
2) "Asker mentioned "creating gels" - So what? "Creating gels" is a culinary application of gelling agents. Not a "culinary creation" of gelling agents, which is nonsensical. You could perhaps use gelling agents to make a culinary creation, but that gets much farther from the meaning of the source text when there is a much more obvious and intelligible alternative in English, namely "application."
3) "Several published texts mention the term "culinary creations"... And it sounds pretentious enough to go hand-in-hand with fancy-dancy recipes using foam and gels and CO2... etc." - Yes, I'm not saying that the term "culinary creation" doesn't exist in English. Obviously it does. I am merely saying that it is incorrect to translate "aplicación" as "culinary creation" in the sentence the asker actually posted. Since you seem to be unfamiliar with cooking terminology in English, I'll tell you that "application" is also a bit pretentious sounding and is frequently used in instructional media and books that are intended to teach chefs. My grandma wouldn't use this term, because it's generally associated with having formal training in cooking, but she would understand it to mean "culinary use" because that's what the word "application" means in general, and it's use isn't restricted to gastronomy. Saws have applications in carpentry and needles have applications in sewing, too. Just go into google and type "Culinary applications of... " and see a list of dozens of sentences that fit my description and wouldn't make any sense at all with "culinary creations."
"PS: I'm not really sure what NB means by a stylised marketing term, or why it wouldn't be suitable for an informative video." - I am referring to the register of the term, which is something that translators need to consider when choosing between different phrases that could all be correct. As your own examples show, the term "culinary creation" is mostly used in advertising language and promotional stuff... such as the Yelp or Pinterest page that you cite.

We would probably need to see the source text, or at least the rest of the sentence to say with 100% certainty, but the translation "Create a video about the culinary applications of gelling agents" is immediately and obviously closer to the meaning of the original sentence than anything with "culinary creation" in it, which I assume would be something like "Create a video about the culinary creations that can be made with gelling agents." By the way, although the dictionary isn't everything, I can't help but note that the words "application" and "use" both appear in the WR Spanish-to-English for "aplicación", while "creation" obviously doesn't because there's really no sense in which these words are connected across these languages.

I'm mystified by the proliferation and popularity of several obviously wrong answers (such as Nielmac's) to your question, and I can't help but note that many of them are proposed and boosted by non-native speakers, although it appears that fluency and being a native speaker aren't necessarily the same thing... Folks really shouldn't be commenting on these threads as if they're definitively correct unless they have actually done some research and are familiar with the applicable field. If you have any other questions about this usage, please feel free to reach out to me!
