I was told that if you want to find the best brand of ice cream taste the regular Vanilla as it's basic without anything else added. Häagen-Dazs has some great plain [NOBABE]Vanilla Ice[/NOBABE] Cream.
When I lived in K.C. I used to fucking love Edy's Tiramisu ice cream. That was awesome. I've gotten some Breyer's Tiramisu gelato but it pales in comparison.
