tips how to make a molded ice ring

Ice cream is universally loved—and homemade ice cream right off the dasher is the most desirable ice cream of all. There are basically two versions. The first is simply sweetened and flavored cream, frozen. The second is a frozen custard made with sweetened cream and egg yolks, which produces a richer, smoother ice cream. They both have their charms, although I lean towards the frozen custard kind. Ice cream can be made with all cream or a mixture of cream and half-and-half or milk. Flavors tend to be more pronounced in ice cream when it is lightened with half-and-half or milk. Heat the cream to dissolve the sugar (or honey). At this point the cream can be infused with other flavorings, such as vanilla bean, coffee beans, herbs, or finely chopped toasted nuts. Let the flavorings infuse for about 20 minutes, then strain them out, and chill the liquid. Fruit purées and extracts are added after the mixture has cooled. Such solid flavorings as chopped fruit, nuts, or grated chocolate are best stirred in after the ice cream has been frozen; added earlier, they impede the freezing process. To make a custard-based ice cream, strain the warm cream, mix with egg yolks, and cook until thick. Chill well before freezing. Ice cream can be frozen in a shallow pan or tray but it will have a much smoother texture if frozen in a machine. The constantly moving paddle, or dasher, breaks up the ice crystals and works a small amount of air into the mix as it freezes. There are a variety of ice cream machines on the market. The traditional machines consist of a wooden bucket that holds a metal canister, which can be surrounded by crushed ice and rock salt. The salt lowers the freezing temperature of the ice, making the ice cream freeze more quickly. The canister is fitted with a dasher that is operated by a hand crank or an electric motor. For best results, chill the dasher and canister before adding the ice cream. There are a number of smaller machines that consist of a double-walled canister that is filled with a liquid coolant. The canister is placed in the freezer until the coolant is frozen solid. When ready, it is filled with the mix and fitted with its motor, which turns a scraping arm. The double-insulated canisters are a bit more convenient but take a while to freeze. If you have the space, store the canister in the freezer so it is ready to go whenever you need it. The mix should be very cold before it is added or it may thaw out the canister before the mix has had a chance to freeze. Only fill the canisters about two-thirds full: the mix will expand as it freezes. Ice-cream machines will freeze ice cream in about 30 to 35 minutes. When just frozen, ice cream is still soft enough that you can stir in such solid flavorings as nuts or candied fruit. The small canister machines have a large hole in the lids for just this purpose. Traditional freezers need to be stopped and opened up. Serve the ice cream right away, or chill it for a few hours to harden further. In a traditional machine you can leave the ice cream in its ice-packed canister right in its bucket (add more ice to cover the top), but don’t leave it in the insulated canister-type machine, which won’t be cold enough to harden the ice cream. Instead, transfer the soft ice cream to a chilled container and put it in the freezer. Pack the ice cream tightly to discourage the formation of any ice crystals. Ice cream will maintain its full flavor for up to a week, but it will lose its sublime texture. When it has frozen quite hard, take the ice cream out of the freezer for a few minutes before serving, for easier scooping.
