"[Photograph: Alexandra Penfold] With little effort you can make an awesome egg cream at home. The ingredients are easy enough to come by: seltzer, milk, and chocolate syrup. I belong to the traditionalist camp that says Fox's U-Bet syrup or bust. But if you must use a different chocolate syrup, well, don't say I didn't warn you. Fox's U-Bet syrup is made either with corn syrup or cane sugar. The cane sugar kind is Kosher for Passover so look for it in the special Passover section of the store and stock up. I find that low-fat milks make the drink a bit watery for my taste, so I use whole milk here. If you have a seltzer dispenser you'll get a nicer, foamier head, but you can still make this drink pouring bottled seltzer off a spoon and stirring vigorously.
