Sour Cream and Brown Sugar Frozen Custard
It looks like ordinary vanilla, but the addition of brown sugar and sour cream lends subtle caramel and tangy notes that will have your friends asking, "What's in this ice cream?"
Vanilla bean paste has a syrupy consistency and is a relatively affordable, mess-free way to get those wonderful tell-tale flecks of real vanilla bean in light-color desserts like ice cream. Find it at specialty grocers or online. (Illinois-based Nielsen-Massey is one great brand.)
