Good for your son! (and you!)
My daughter is not a big fan of vinegar, so there are times when she wants no part of being anywhere around when I’m cooking certain jellies and sauces, but other than that she loves playing in the kitchen and experimenting with flavorings in our standard stuff.
We are adding a new thing to our Sunday afternoon regular weekly food planning/preparing because there are no longer snacks offered for sale in the cafeteria. We’re going to make at least one kind of cookie and another type snack, chips, pretzels, whatever we pick.
Sounds like you’re a great parent, and raising a good young woman, well done.
Shame many today do not have that ethic you do, and understand that when you have kids then your life is their life.
