I was thinking of having “If you change the ingredients in a recipe, results will vary” tattooed on my forehead, but there wasn’t enough room. (Although if my hairline keeps receding at this rapid pace, it may happen sooner than you think.) When I used to teach classes, folks were always wanting to tinker with recipes, especially ice cream, replacing the cream with what-have-you. Or to replace the sugar with something else. I’m not sure why, because I spend an inordinate amount of my life developing and testing recipes to get them just right.
Unless I’ve personally tested it, it’s pretty hard to give my nod of approval and tell what will and what won’t work in recipes, especially when it comes to swapping out sweeteners and dairy products since their counterparts behave quite differently than one might think. Ice cream, of course, depends on cream to give it that particular texture and flavor. But I do like and use non-dairy alternatives at home on occasion and saw no reason why I couldn’t churn up a batch of ice cream without a drop of dairy.
