Mom and dad, both grandmothers and many of my kinfolk loved buttermilk but I never could stomach it. One of my earliest memories is eating at a restaurant with parents, me about 3 or 4 years old, and dad sneaking and having the server give me a glass of buttermilk instead of my usual whole sweet-milk. First sip I gagged and threw the glass as far and as hard as I could breaking it and spit as much as I could that I already had in my mouth all over the counter top. Don't mind buttermilk pancake, biscuit, etc., mixes but still can not drink it straight.
