Does tasting food without swallowing break a fast?

A bit of context here. My wife and I do a lot of baking and experimental recipes for her business, and we have to taste the food (obviously) to see if it was successful. We usually do the baking in the evenings, after dinner, which is outside my eating window. I don't mind not eating what we bake, my cravings are pretty well under control, but I worry that even just tasting the food and spitting it out could break my fast, I was wondering if the folk here could shed some light on whether or not it does.

Thank you kindly in advance!
