A synonym for "picky" with a positive connotation (food)?

We're very picky about the ingredients we use.

In that context, what's a synonym for "picky" with a positive connotation, that denotes that we care very much about the quality of the ingredients?

  • Selective lacks emotion.

  • Choicy is a bit over-the-top.

Drawing a blank here.

I saw the other question about "picky", but the context is not the same:
Adjective for exclusive/selective/picky with positive connotations


Discerning.

Having or showing good taste or judgment; discriminating.

Collins English Dictionary, as found at thefreedictionary.com


The following would work:

"We're discerning about the ingredients that we use."

However, as pointed out to me in the comments, the more common usage is:

"We're discerning in the ingredients that we use."


Selective

We are very selective in choosing our ingredients.

  1. tending to choose carefully or characterized by careful choice (Free Dictionary)

Discriminating

: liking only things that are of good quality : able to recognize the difference between things that are of good quality and those that are not

In the context of being picky about food ingredients, readers should understand this meaning and its positive connotation. However, I worry that semi-literate readers would confuse it with the word discriminatory.


A word in the same register as picky but without the negative connotations that picky sometimes has, is choosy.

We're very choosy about our ingredients.


"We're very conscientious about the ingredients we use"

conscientious adjective: very careful about doing what you are supposed to do: concerned with doing something correctly. (Merriam-Webster online)
