How to Freeze Lemon Posset

Freezing lemon posset is surprisingly easy. You do need to consider how you want to serve the posset beforehand. If you like to serve lemon posset in individual portion containers, then you need to freeze it in these containers.

If you aren’t too worried about the presentation of the posset, then you can freeze it in one large container and scoop it out into bowls.

Let’s dive in and find out how to freeze lemon posset.

  1. Cook and Cool
    Make and cook your lemon posset. Pop it into the containers you plan to freeze it in and allow it to cool.

3 Tips for Freezing Lemon Posset

Now you know how to freeze it, we’ve got our 3 top tips which we strongly recommend following when freezing lemon posset to have the best results:

  • Blend – If you find your lemon posset ends up too grainy in texture, then you can pop it into a blender or whisk it up again. It might not ever be quite as perfect as it was fresh, but it will still be delicious.
  • Try Using Bags – If you don’t have any containers, then you can freeze your lemon posset in freezer bags instead. You need to make the bags as airtight as possible, so pop a straw into the bag and suck out the air before you seal it.
  • Avoid Entirely – If you don’t want to lose any of the delicious flavour and texture you love about a lemon posset, then you can always pop it into the fridge instead of freezing it. It will keep in the fridge for up to three days which might be enough time to eat it without freezing.

How Long Can You Freeze Lemon Posset?

Lemon posset is a cream-based dessert, and you do need to take care because it can spoil and change in texture while frozen. So you should only keep it in the freezer for up to two months before defrosting and using it.

How Do You Defrost Lemon Posset?

For best results, you should defrost the lemon posset in the fridge slowly. This method ensures that any crystals that form in the dessert have the best chance to dissipate.

So take your lemon posset out of the freezer and pop it into the fridge for several hours to defrost. Then serve straight from the fridge.

Can You Refreeze Lemon Posset?

No, you should not refreeze lemon posset. You may notice there are some changes in the texture of the posset, and this will only get worse the more you freeze it.

You also need to be careful of spoiling and any bacteria growth. Refreezing could end up with you being sick.

Does Lemon Posset Freeze Well?

High dairy content foods tend not to freeze as well as other foods because of the high fat and protein content. The molecules separate from the liquids, and you can end up with separated cream.

Due to the high dairy content of a lemon posset, you might find that it is slightly grainy in texture. If you need, you can stir it before serving or even pop it into the blender and blend to try and mix the posset back up again.

  1. Thanks for the information on freezing lemon possets. I froze 25 passion fruit possets very successfully in sturdy glass ramekins. I filled them, cooled, open froze and then vac packed them on soft pack. 5 per large vac pack bag. Defrosted them in the fridge overnight. Absolutely delicious and completely perfect. Thanks
