How to Make Ice Cream

When my mother’s family would get together for summer holidays or even Thanksgiving and Christmas, they would make ice cream. Homemade ice cream is wonderful stuff. The texture of it is more similar to soft serve ice cream unless allowed to freeze, and you can control the ingredients that went into it.

The hardest part about making ice cream is finding an ice cream maker, and maybe having to put up with the noise for 20 to 40 minutes, depending on the model. I recommend getting an electric ice cream maker because making ice cream is too time consuming to have a manual crank, though there are now ice cream maker balls that you roll around.

I have made small amounts of ice cream by using a double bag method, where the ingredients are in a smaller bag placed in a larger bag with ice and mixed up. The same time I made ice cream in small bags, the organizers served us all the ingredients already mixed and then frozen. It wasn’t as good because it was missing an ingredient – air. The stirring action adds air, making it “light and fluffy,” so it tastes better. I do recommend that if you use this bag in bag method to rinse off the inner bag before opening to remove any salt and therefore prevent salt contamination inside. It happened to me.

The process, especially with a machine, is to have crushed ice and rock salt in the bucket around the canister holding the ice cream materials. The ice is to chill the ingredients, and the rock salt helps lower the temperature of the melted ice. I recommend that the churning with a machine take place with the bucket in a large sink, bath tub, or outside, as the ice will melt and make a mess. Also, secure the canister and motor in the bucket before adding ice. Adding ice before doing this will push the canister into difficult angle for securing the motor.

There are two main types of homemade ice cream – custard style, which makes a custard base by lightly cooking eggs, and American style, which is just cream and sugar.

Applejack

Traditional applejack is like making brandy, but instead of heating up to remove the alcohol from the water, applejack is frozen to remove the water from the alcohol. This technique is sometimes referred to as “cold distilling.”

Making applejack was once popular in the New England area of the United States. It was made by putting a bucket of apple cider outside in the winter where temperatures drop below 0⁰ F and the water in the cider would freeze, which was then scooped off, leaving behind the alcohol. This process is repeated several times to remove most of the water and concentrate the alcohol.

The colder the temperatures are, the higher the applejack proof can become. In Wines & Beers of Old New England, Sanborn C. Brown estimates that 0⁰ F can yield a 28 proof or 14 percent alcohol by volume applejack. If the temperatures were around -30⁰F, the applejack could reach 65 proof. Therefore, it can be as weak as wine or as strong as brandy depending on where it was made and how cold it got.

Annie Proulx and Lew Nichols in Cider: Making, Using & Enjoying Sweet & Hard Cider do mention that “Applejack makers are concerned with getting the most alcohol out of the weather and the cider for their efforts, so” they will add extra sugar and use wine yeasts that can make a higher alcohol apple wine. This process is done during the fall so that the freezing process can begin in January. However, a high alcohol apple wine does not increase the applejack proof, but the temperature does, as previously described. They describe applejack “very flavorsome, but dry, and many prefer to sweeten it to taste before bottling” (page 167).

The real problem with cold distilling is that the finished product has an increased level of toxins. Fermentation creates a few toxins, such as esters and aldehydes, but they are at low dosages that really do not harm the body. With regular heat distilling, these toxins are the first to boil off at the low temperatures in what is called the “head”, and they are set aside for industrial uses such as making lacquer, nail enamel, and cleaning solvents. It smells very much like finger nail paint remover. The second part of heat distilling is the “heart”, which is the consumable ethyl alcohol. The last part, the “tails”, is more toxins such as fusel oils and amyl and propyl alcohols, which are harmful if swallowed at these higher concentrates. These three sections are common to every heat distillation, and can be separated by smell and timing in the distillation process. However, with cold distilling, these toxins are not removed, and the constant removal of water in cold distilling further concentrates them. As a result of the toxins in applejack, it is well known for having a “kick” and then leaving the drinker with a horrible hangover the next day, despite being possibly a lower alcohol content than other higher proof heat distilled spirits.

To read more on the process, check out Annie Proulx and Lew Nichols’ Cider: Making, Using & Enjoying Sweet & Hard Cider and Ben Watson’s Cider: Hard & Sweet. Remember, even though applejack is not distilled with heat, the process of cold distillation is still considered illegal in the United States without a proper permit.
