SECTION 2: FULL RECIPE
PREP TIME:About 10 minutes
HEATING TIME:About 35 minutes
INGREDIENTS:Cream Full-fat, semi-skimmed, or skimmed milk Unrefined sugar Skimmed milk powder Egg yolks Earl Grey tea leafs 4 tablespoons Sea salt 1/4 teaspoon
Produces just under 900 ml (0.95 quarts) of ice cream mix
1. THE IMPORTANCE OF MILK FAT
Milk fat contributes significantly to the rich, full, and creamy flavour and to the smooth texture of ice cream (Goff & Hartel, 2013). Not enough milk fat is likely to produce ice cream that is coarse or sandy, whereas too much will likely result in a heavy buttery texture. Above is the spreadsheet I use to calculate my mixes and I’ve included it for you guys to accurately calculate the quantities of milk and cream that you’ll need. It’s based on the mix formulation calculations in Ice Cream (7th ed) (2013) by Goff & Hartel, which I highly recommend reading.
It’s important that you check the fat content percentage of the milk and cream that you’ll be using. Here in the U.K, our double cream and skimmed milk contain between 47.5% and 50.5% and less than 0.5% of milk fat respectively. You can use full-fat, semi-skimmed, or skimmed milk.
To start, enter the fat percentage of your cream in the yellow Cream Fat % cell located on the top left of the spreadsheet. Do the same for the milk fat percentage in the yellow Milk Fat (%) cell. PRESS ENTER, OR CLICK ON A DIFFERENT CELL, FOR THE SPREADSHEET TO UPDATE. The spreadsheet will then display the quantities of milk, cream, sugar, egg yolks, and skimmed milk powder needed (in grams) in the cells in blue.
2. PREPARING AN ICE BATH
Before you start preparing your mix, take a large bowl and fill it with enough ice to make an ice bath. Have a large zip-lock freezer bag ready next to the bowl, along with some table salt. We’ll be using the zip lock bag and ice bath to ensure that the mix is cooled as quickly as possible after heating. This minimises the time the mix spends in the ‘danger zone’, between 5°C (41°F) and 65°C (149°F), where bacteria likes to multiply. The longer your mix spends in this temperature range, the more bacteria is likely to multiply and impart an undesirable taste and smell.
3. HEATING THE MIX
Weigh your pan and record its weight. We’ll use this weight to check whether we’ve achieved the desired 13% reduction after 25 minutes of heating.
Once you’ve prepared the ice bath and weighed your pan, add the sugar and skimmed milk powder followed by the egg yolks. Mix the yolks, sugar and skimmed milk powder to help prevent the yolks from curdling during heating.
Add the cream and milk and spend a good minute or so mixing all the ingredients before you switch on the heat.
Over a medium heat, heat the mixture until the temperature reaches 71°C (160°F), making sure that you’re constantly stirring. You’ll risk burning the milk proteins and curdling the egg yolks if you do not constantly stir the mix. It takes me 10 minutes to get my mix up to 71°C (160°F).
Once the temperature reaches 71°C (160°F), turn the heat down to low, move your pan slightly off the heat, and continue heating and stirring until the temperature reaches 72°C (162°F). Use a food thermometer to keep your mix at 72°C (162°F) for 25 minutes, adjusting the position of your pan to help regulate the temperature. Don’t worry if you go slightly over 72°C (162°F); just try and keep the temperature as close to 72°C (162°F) as you can.
4. COOLING THE MIX
After 25 minutes of heating at 72°C (162°F), take the pan off the heat and weigh it. If the weight is greater than 1044g plus the weight of the pan, place it back on the heat and continue heating for another 2-3 minutes or until you get the weight down to 1044g plus the weight of the pan.
Carefully pour the mix into the zip-lock bag, followed by the Earl Grey tea leafs and sea salt, and seal. Place the sealed bag in the ice bath and pour about a tablespoon of salt onto the ice to lower the temperature and cool the mix faster.
Once the mix has cooled to below 5°C (41°F), place the zip-lock bag in the fridge and leave overnight to age and to extract the bergamot flavour compounds.
5. CHURNING THE MIX
Once you’ve aged your mix overnight, carefully strain it using a large spoon to press down on the tea leafs to extract as many flavour compounds as possible. Once you’ve strained the mix, pour it into your machine.
TIP#1 – FREEZER BOWL WALL TEMPERATUREIf you’re using an ice cream machine with an in-built compressor, with the bowl in the machine, switch on the compressor and leave it running for 15 minutes before adding the mix. This will ensure that the freezer bowl is as cold as possible when the mix is added, which increases the rate of nucleation and reduces residence time.
TIP#2 – EFFICIENT HEAT TRANSFERIf you’re using the Cuisinart ICE 30BC, use your thumb to push the dasher against the side of the bowl as soon as you pour in the mix. This will ensure that the dasher scrapes off the layer of ice that freezes to the side of the bowl. Any ice that is frozen to the side of the bowl will act as an insulator, slowing the release of heat from the ice cream to the bowl and increasing the residence time. Goff & Hartel (2013) note that even a very thin layer of ice remaining on the bowl wall can cause a dramatic reduction in heat transfer.
Use a spoon to push along any static lumps of ice cream and ensure that the mix is constantly moving whilst in the machine. Static lumps will likely take longer to freeze, resulting in greater ice crystal growth.
6. DRAW TEMPERATURE
Your ice cream will be ready when it develops a nice dry, stiff texture, and starts forming ribbon-like swirls. It should have a draw temperature (the temperature at which the partially frozen ice cream is removed from the machine) of between -9°C and -12°C (15.8°F and 10.4°F) with a lower draw temperature usually resulting in smaller ice crystals (Arbuckle, 1986).
Below are the residence times and draw temperatures for the domestic machines I’ve tried:
- Lello Musso Pola 5030 Dessert Maker: 900 ml (0.95 quarts) mix – 13 minutes, -11°C (12.2°F).
- Lello 4080 Musso Lussino 1.5-Quart Ice Cream Maker: 600 ml (0.63 quarts) – 16 minutes, -11°C (12.2°F).
- Cuisinart ICE-100 Ice Cream and Gelato Maker: 900 ml (0.95 quarts) mix – 35 minutes, -10°C (14°F).
- Breville BCI600XL Smart Scoop Ice Cream Maker: 700 ml (0.74 quarts) – 34 minutes, -9°C (15.8°F).
- Whynter ICM-200LS: 900 ml (0.95 quarts) mix – 28 minutes, -10°C (14°F).
- Cuisinart ICE 30-BC: 900 ml (0.95 quarts) mix – 34 minutes, -11°C (12.2°F).
7. EXTRACTION TIME
The extraction time (the time it takes to get your partially frozen ice cream out of your machine and into the freezer) has a considerable effect on ice crystal size. This is because as you extract your ice cream from the bowl and into a plastic container, it spends time at room temperature. At this relatively warm room temperature, some of the ice melts from the large ice crystals and the crystals that were initially small melt completely. When you then get your ice cream into your freezer for the static freezing stage, the melted ice re-freezes onto the large ice crystals that survived. The result is that the total number of ice crystals is reduced and their size increases, resulting in coarse or grainy texture.
TIP#3 – QUICK EXTRACTIONJust holding ice cream at a relatively warm room temperature as you extract it from your machine results in an increase in mean ice crystal size and a decrease in the number of ice crystals present. It’s therefore important that you extract the ice cream from the freezer bowl and get it into your freezer as quickly as possible.
8. THE STATIC FREEZING STAGE
At a draw temperature of between -9°C and -12°C (15.8°F and 10.4°F), your ice cream will have a consistency very similar to that of soft serve ice cream and will need to be placed in your freezer to harden. After about 4 hours, depending on your freezer, your ice cream will have a nice firm scoopable consistency, somewhere around -15°C (5°F), and be ready to serve.
9. SERVING YOUR ICE CREAM
Serve your ice cream at around -15°C (5°F). As the serving temperature is increased from -14.4 (6.1) to -7.8°C (18°F), flavour and sweetness become more pronounced.
