Homemade ice cream without a machine: rich vanilla, sorbet and banana ice cream
Two-ingredient ice cream with condensed milk, a classic custard-based vanilla, why ice crystals form and how to prevent them, sorbet with the right amount of sugar, frozen-banana ice cream, ice lollies and storage tips.
Why ice crystals form
Shop-bought ice cream is soft and smooth because it's churned while freezing: air and constant movement stop water gathering into large crystals. Homemade ice cream frozen in a tub without stirring often turns icy — the water in it simply freezes.
There are three ways to fight crystals: whip air into the base (whipped cream); add things that lower the freezing point (sugar, a little alcohol) and stop crystals growing (fat, egg yolks, condensed milk); and stir the ice cream while it freezes.
Two-ingredient ice cream
The simplest recipe, no machine or stirring. Condensed milk is very sweet and thick — it stops ice forming — and whipped cream makes the ice cream airy.
- 500 ml 33–35% cream, very cold
- 1 can sweetened condensed milk (380 g), chilled
- 1 tsp vanilla extract or the seeds of a vanilla pod, a pinch of salt
- Whip the cream to soft but stable peaks.
- In another bowl mix the condensed milk with the vanilla and salt, fold in a third of the cream, then gently fold in the rest.
- Spoon into a container, cover and freeze for at least 6 hours, ideally overnight.
Classic custard-based vanilla
A custard base (crème anglaise) makes the creamiest, smoothest ice cream. The yolks act as an emulsifier and give a velvety texture.
- 250 ml 3.2% milk, 250 ml 33% cream
- 4 egg yolks, 100 g sugar, a vanilla pod or 1 tsp extract
- Heat the milk and cream with the vanilla almost to the boil.
- Whisk the yolks with the sugar until pale. Pour in a third of the hot milk in a thin stream, whisking — so the yolks don't scramble.
- Return everything to the pan and cook over low heat, stirring constantly with a spatula, to 82–84 °C, until the custard coats the spoon and a finger drawn through it leaves a clear line. Don't boil — the yolks will curdle.
- Strain, cool over a bowl of ice and refrigerate for at least 4 hours, ideally overnight — the base matures and the ice cream is smoother.
Freezing without a machine
Without an ice cream maker, a custard base is frozen with stirring.
- Pour the chilled base into a shallow metal container — metal conducts cold faster.
- Put it in the freezer. After 40–45 minutes take it out and whisk thoroughly, breaking up the frozen edges.
- Repeat every 30–40 minutes 3–4 times until the ice cream is thick but still soft.
- Then smooth it, cover and leave to freeze completely for 2–3 hours.
- You can blitz it with a stick blender at the last stir — it becomes even airier.
Sorbet: sugar isn't just sweetness
Sorbet is fruit ice with no milk. In it, sugar controls texture: too little and it freezes into a block of ice; too much and it won't set at all.
The right sugar concentration for a sorbet base is 20–30%. In practice: per 500 g fruit purée, 100–150 g sugar as a syrup (sugar and water 1:1, heated until dissolved and cooled). Sweet fruits (mango, banana) need less, sour ones (lemon, raspberry, blackcurrant) more.
The juice of half a lemon brightens any fruit sorbet. 1–2 tbsp vodka or liqueur per litre of base makes it softer: alcohol doesn't freeze. Don't add more — it won't set.
Banana ice cream
The simplest, healthiest "ice cream" has one ingredient. Frozen bananas in a blender turn into a creamy mass like soft-serve — no sugar or cream.
Peel ripe, spotty bananas, slice them and freeze on a tray for at least 6 hours. Blitz in a powerful blender or food processor for 3–5 minutes, stopping to scrape down the sides. First it turns crumbly, then creamy.
Add-ins: 1 tbsp cocoa, peanut butter, a handful of frozen berries, a pinch of cinnamon, a spoon of honey. Eat straight away as soft-serve or freeze for another 1–2 hours to firm up.
Ice lollies and popsicles
Ice lollies are the simplest ice cream for children. Pour juice or purée with a little sugar into moulds, add sticks and freeze for 4–6 hours.
Pure juice freezes very hard. For softer lollies, mix juice with fruit purée or yoghurt, or add 1 tbsp honey per 250 ml. Layered lollies: pour each layer once the previous one has set — 30–40 minutes.
To release a lolly from its mould, dip the mould in warm water for 10–15 seconds.
Safety and raw eggs
Some old recipes make ice cream with raw eggs. That isn't safe: raw eggs can carry salmonella, and freezing doesn't kill it.
Use egg-free recipes (with condensed milk) or a custard base heated to 82–84 °C — salmonella dies at that temperature. Cool the base quickly over ice and don't leave it at room temperature.
Storage and serving
Homemade ice cream without stabilisers is best in the first 3–7 days. It keeps longer — up to 2–3 weeks — but gets harder and can grow ice crystals.
To stop an icy crust forming, press cling film directly onto the surface, then put the lid on.
Homemade ice cream is harder than shop-bought. Take it out of the freezer 10–15 minutes before serving, and for neat scoops dip the scoop in hot water before each one.
Questions and answers
Why is my homemade ice cream rock hard?＋
Too little sugar or fat, it wasn't stirred while freezing, or the base has too much water (milk instead of cream). Add 1 tbsp alcohol or glucose syrup and use 33% cream.
Can I make ice cream without cream?＋
Yes: from frozen bananas, as a fruit sorbet, or with coconut milk — it's rich enough for a creamy texture.
Can I use less sugar?＋
A little, but sugar is what keeps it soft. Without it ice cream freezes solid. Better to replace some sugar with honey or condensed milk than to cut it.
Why didn't my condensed-milk ice cream set?＋
The cream wasn't whipped enough, or the condensed milk was added roughly and the cream collapsed. Whip cold cream to firm peaks and fold gently.
How much does a recipe make?＋
The condensed-milk recipe makes about 1 litre; custard vanilla with 500 ml liquid makes about 700 ml — volume rises slightly with the air during freezing.
