Places that sell real frozen custard are hard to find any more. Two of the best are neighbors in the Manayunk-Roxborough neighborhoods of Philadelphia. They used to be (almost) directly across Ridge Avenue from each other going head to head. They both sell ice cream and frozen desserts but the custard is what they started with and it’s the real thing: homemade eggs, cream and sugar (and not too much sugar). I never could develop a preference for custard at one or the other. Often my choice depended on which way I was driving on Ridge (I’d take the one on the right).
Still on Ridge is Custard & Cakes Creamery (frozen cakes) at 5641 Ridge Ave (at Hermit) in Roxborough.
The other is Dairyland Frozen Custard 4409 Main Street in Manayunk. I think Dairyland lost out in relocating. They are now in Manayunk’s somewhat trendy stretch of boutiques and restaurants. The former location is now Rita’s Water Ice (they sell something they call “custard” but avoid it) across from C&C Creamery. Custard & Cakes still remains in a diverse residential neighborhood where kids and families can walk (or bike) over to get custard. Still if you are looking to explore Manayunk, Dairyland is worth a stop.
