I wanna know. Eggnog, which is only good for adding liquor, is fucking disgusting. I will engage in good faith arguments for why there is eggnog ice cream, but there is a reason this was in the discount end cap section, so you got an uphill battle already.
Again, understandable
I don't have dairy issues and IIRC the pre-mixed boozy stuff you can buy doesn't actually have dairy in it, just carrageenan and vanilla
I've also never had a mudslide but I bet it's pretty good
That premixed shit has a super weird aftertaste to me
