Melbourne's Fastest Nang Delivery Service
You have been beating the same bowl of cream for six minutes and it still looks like cream. Or it went perfectly until the moment it turned grainy and yellow and started to smell like butter. Both of those have a cause, and in almost every case the cause is one of six things.
The fastest way to sort it out is to check the carton before you check your technique. Cream needs roughly 30 per cent fat to hold a foam at all, so if the tub in your hand is light thickened cream at 18 per cent, nothing you do with the beaters is going to save it.
The short answer
| What went wrong | What to do about it |
|---|---|
| Cream is under 30 per cent fat | Start again with thickened or pure cream |
| Cream is warm | Chill it back to fridge temperature and rechill the bowl |
| Grease or water in the bowl | Wash and dry the bowl and beaters, use metal or glass |
| Too much sugar added too early | Whip to soft peaks first and add sugar after |
| Cream is close to its use by date | Use it in a sauce and buy fresh cream for whipping |
| Whipped past firm peaks | Fold in a splash of unwhipped cream by hand |
Start with the fat percentage
Whipping works because fat globules clump together into a network that traps air. Below about 30 per cent fat there is not enough fat in the liquid to build that network, so the air you beat in escapes as fast as you add it. This is physics rather than technique, and it is the reason most whipping failures in Australian kitchens happen.
Here is what is actually on the shelf.
| Cream | Fat | Whips |
|---|---|---|
| Thickened cream | About 35 per cent | Yes, and holds well |
| Pure cream | About 35 per cent | Yes, softer and weeps sooner |
| Light thickened cream | About 18 per cent | No |
| Light cooking cream | About 18 per cent | No |
| Double or rich cream | 45 to 55 per cent | Already thick, whips to butter fast |
The full breakdown of what each of these is actually for sits in our Australian cream guide.
Can you whip thickened cream
Yes. Thickened cream is the easiest cream in the Australian supermarket to whip and the most forgiving of the lot.
It sits around 35 per cent fat and it has an added thickener, usually gelatine or a vegetable gum such as 407. That additive is doing roughly the same job a home stabiliser does, which is why thickened cream holds its peaks for longer than pure cream and why it tolerates a bit of rough handling. The supermarket brands are all in the same range, so Bulla, Devondale, Pauls and the house brands all behave the same way in a bowl.
Long life thickened cream in the carton off the shelf whips too. It takes longer than fresh, sometimes twice as long, and it needs to be properly cold, so put it in the fridge overnight rather than pulling it from the pantry an hour before.
Can you whip light thickened cream
No, and this is worth saying plainly because a lot of pages hedge on it.
Light thickened cream sits around 18 per cent fat, which is well under the threshold where a stable foam can form. What you get after five minutes of beating is a thin froth that looks briefly promising and then collapses back into liquid, usually while you are carrying it to the table. Adding gelatine, cornflour or milk powder to it produces something that holds a shape but tastes and feels like set milk rather than whipped cream.
The same limit applies to a dispenser. Charging light thickened cream with N₂O gives you a foam that falls apart in under a minute, because the gas needs fat to dissolve into. There is no equipment answer to a fat problem.
Six reasons cream will not whip
The cream is too warm
Fat has to be solid enough to hold its shape. Above about 10 degrees the globules soften and slide past each other instead of locking together. Cream straight from the back of the fridge at 4 or 5 degrees whips in a couple of minutes, and the same cream left on the bench for half an hour on a warm day can take twice as long or refuse entirely. In an Australian summer kitchen this is the single most common cause.
The bowl or the beaters were not clean
A film of oil or butter left on a bowl will stop a foam forming, and so will a few drops of water. Plastic bowls are the usual culprit because plastic holds grease films that survive a quick rinse. Use stainless steel or glass, wash it in hot soapy water, dry it properly, then put the bowl and the beaters in the freezer for ten minutes before you start.
Sugar went in too early
Sugar competes with the fat for the water in the cream and slows aeration down. A tablespoon at the start makes no real difference, but four tablespoons will noticeably hold the cream back. Whip to soft peaks first, then add the sugar and finish. Icing sugar is the better choice over caster because the cornflour in it helps the foam hold.
The cream is old
Cream approaching its use by date whips badly even when it still smells fine, because the fat structure degrades before the cream sours. If it has been open in the fridge for a week, use it in a pasta sauce and open a fresh carton for whipping.
The bowl is too small
Cream roughly doubles in volume, so 300ml of cream needs a bowl that comfortably holds 700ml or more. In a bowl that is too small the beaters cannot move the cream through the air and you end up stirring rather than whipping.
You are using a blender or a food processor
Both spin far too fast and take cream from liquid to butter in about twenty seconds with no usable stage in between. Whisk attachment on a stand mixer, hand beaters, a balloon whisk or a dispenser. Not a blender.
You over whipped it
Over-whipped cream goes through a sequence and you can catch it at any point along the way if you are watching.
First the surface loses its gloss and turns matte. Then it goes grainy, like very fine curds. Then the fat separates out completely and you are left with lumps of butter sitting in thin buttermilk. The first two stages are recoverable and the third is not, though at that point you may as well keep going, drain it and call it butter.
How to fix over whipped cream
If the cream is matte or lightly grainy but still one mass, stop the mixer and pour in one to two tablespoons of cold unwhipped cream for every cup you started with. Then fold it through by hand with a whisk or a spatula, slowly, until the texture comes back together. Do not put the beaters back in, because the machine will take it straight past the point you are trying to return to.
This works because you are adding back liquid fat that has not yet been shorn into the network, which loosens the structure. It usually gets you most of the way back, though the cream will be a little denser than it would have been.
If it has already split into butter and buttermilk, that is done. Squeeze the butter out, salt it, and put it on toast.
How long thickened cream takes to whip
With hand beaters or a stand mixer on medium high speed, 300ml of cold thickened cream takes about two to three minutes. Long life cream can take four or five. By hand with a balloon whisk it is closer to six to eight minutes of steady work, and the trick there is to move the whisk in wide circles to pull air in rather than beating in one spot.
Slow down as you approach the finish. The last thirty seconds are where soft peaks turn into firm peaks and firm peaks turn into butter, and on a machine that gap is a matter of a few seconds. If you are whipping ahead of time, stop at soft peaks, since it will firm up a little in the fridge on its own. Our guide to making whipped cream covers where each peak stage actually sits.
The failure you cannot have with a dispenser
A cream dispenser does not fix a fat percentage problem and it does not fix warm cream. What it removes entirely is over-whipping, because the foam does not form in a bowl at all. The cream sits in the canister as liquid with nitrous oxide dissolved into it, and the foam forms in the two centimetres between the valve and your plate. There is no window to overshoot, no grainy stage, and no butter.
That is the reason commercial kitchens use them on dessert sections. A dispenser gives the same result on a busy Saturday night as it does on a quiet Tuesday, regardless of who is holding it, and the cream in it keeps for a week or more rather than a couple of days. Nangstar stocks the dispensers and the chargers that run them.
Frequently asked questions
Why is my thickened cream not whipping
Nine times out of ten the cream is too warm or the bowl was not clean. Chill the cream to fridge temperature, wash and dry the bowl and beaters properly, put both in the freezer for ten minutes and try again. If it still refuses, check the carton is thickened cream and not light thickened cream.
Can you whip light thickened cream in Australia
No. At around 18 per cent fat it is below the level needed to form a stable foam, and no amount of extra beating changes that. Use thickened or pure cream instead.
Can you whip thickened cream by hand
Yes, and it gives you far more control than a machine does. Use a balloon whisk and a chilled metal bowl, work in wide circles, and expect six to eight minutes for 300ml. Hand whipping makes over-whipping almost impossible.
How do you make whipped cream hold its shape for longer
Whip to firm rather than soft peaks, keep it cold, and either fold in a stabiliser such as a teaspoon of icing sugar with cornflour or use a charged dispenser, which holds the cream as a liquid until the moment you serve it.
Can you fix cream that has turned to butter
Not back into whipped cream. Once the fat and the liquid have fully separated the structure is gone for good. Drain off the buttermilk, rinse the solids in cold water, add a pinch of salt and use it as butter.
Does cream whip better with sugar in it
Slightly worse at the start and slightly better at the end. Sugar slows the aeration down, so add it once the cream is at soft peaks rather than at the beginning, and use icing sugar rather than caster if you want the finished cream to hold.
