2 Failproof Ways to Make Irish Moss Gel at Home

Make Irish Moss gel at home using a raw method, or you can add a little heat to speed up the process if you are in a rush. Note that heat may compromise the nutrient density of the gel so raw is preferred (if time permits!).

Please follow these instructions step-by-step, and you will be delighted with the results! You will need to set aside a little time to make Irish moss gel (which is also known as Sea moss gel) at home, but it is well worth the effort!

Make Irish Moss gel using either the raw (overnight soaking) or simmering method in these failproof recipe suggestions.

Irish Moss can be used in vegan and vegetarian cooking. Add it to your morning smoothie to boost nutrients and build immunity, or use it in DIY beauty treatments.

2 Ways to Make Irish Moss gel (Sea Moss gel) at home

Make your own Irish Moss gel at home, using either of these 2 tried and tested methods: 

  1. Simmer using a low heat (never boil your sea moss) or
  2. Soak it overnight if you prefer a raw sea moss gel.

With either of these methods, before you start please:

  1. Rinse the raw Irish Moss seaweed thoroughly under water, this is a beautiful wild harvested product. The aroma of ocean that comes out of a packet of our Irish Moss is a good indication this is an authentic product. However it may be off putting to some. As you rinse it, the ocean flavour will diminish and the colour will lighten.
  2. Ensure you have a clean, airtight container for storage
  3. Once you have made the Irish Moss gel (using either of these methods) place in your clean container with a lid and then put it in the fridge. A gel will form after about 2 hours.
  4. The gel will last approximately 3 weeks in the fridge. You can also freeze it if you have made too much, and this should last for up to 3 months.
  5. A typical daily serving is around 1-2 tablespoons of the gel but experiment with what suits you best.

Ingredients required for either method:

  • 1 cup Irish moss raw seaweed
  • up to 2 cups spring water/filtered water
  • Sieve
  • Clean airtight container
  • Sieve (and spoon to scrape) or blender

1.Make Irish Moss Gel Using the Simmer Method

1.  Add one cup (or less if you require a soft set) of cleaned Irish Moss to two cups of filtered/spring water.

2. Simmer slowly until most of the seaweed has dissolved (20 -25 minutes). Do not boil.

3. Blend with a blender until smooth, or if you prefer, remove any undissolved fragments by straining the solids through a sieve. Use a spoon to scrape the sieve if required.

4. Pour gel into a clean jar or mould to set.

2.Make Irish Moss Gel Using The Raw, Overnight Soaking Method

This option takes a little longer but it’s worth it if you prefer raw ~ this preserves the nutrients better than using heat.

1.  Put a cup of cleaned Irish Moss into a bowl and cover it with enough filtered/spring water to submerge the seaweed (with a little extra over the top as the seaweed will expand and absorb the water.  Cover it and leave for 12 – 24 hours. You don’t need to put it in the fridge.

2.  As it soaks the seaweed will expand and absorb the water. It becomes gooey/slippery to touch.

3. After soaking, use this mixture as is, or blend with a blender until smooth. Don’t throw any of the water the moss has been soaking in away*, OR, if you prefer, remove any undissolved fragments by straining the solids through a sieve. Use a spoon to scrape the sieve if required.

4. Pour into a clean jar or mould to set

* Use it on your skin or add it to your house plants if you don’t want to use it in your gel.

How Long Does Irish Moss Gel Last?

If stored correctly in an airtight container, Irish moss gel can last 3-4 weeks in the fridge, but check first if you have left it longer than 3 weeks! It can be frozen for up to 3 months.

Why do you suggest we make Irish Moss gel and not purchase it already made up?

There are many ways to purchase Irish Moss but we prefer going back to source – the raw seaweed. This way, you know what is in it! Yes, you will need to set aside a little time to make up the gel from this raw seaweed, but you can rest assured the goodness from the ocean has not been processed out of it. With additional processing and heat, seaweeds nutrient density can be damaged.

Some also offer made up gel, which may have a limited shelf life by the time it reaches your shopping trolley and have preservatives and flavours added to it.

We prefer to offer the raw ingredients so you can control the quantity you need, when you need it, and know the quality is optimal with no nasties added.

Why is the colour of Irish Moss red/brown colour and not blonde?

We use a species called Chondrus crispus which grows in the nutrient rich north Atlantic ocean and is a darker colour of a similar species of seaweed which grows in the warmer waters around parts of Asia and the Caribbean. Additionally we dry this species indoors to keep it food grade and reduce risk of contamination during the drying period. As a result it retains its darker colour and does not become sun bleached.
