So Easy!

This delicious Rhubarb Cordial is easy to make, perfect for a hot day. The great thing about making your own Cordial is that you know every ingredient in it, unlike some shop bought ones that are loaded with artificial sweeteners and other unnecessary ingredients.

Ingredients for Rhubarb Cordial

Rhubarb washed and cut into chunks. I grow my Rhubarb on my Allotment, but you can buy it fresh, frozen or tinned from the supermarket. If using frozen Rhubarb, thaw before adding to recipe.

Sugar Either Caster or Granulated sugar will work fine.

Water Tap water or filtered water

Orange Juice Juice squeezed from 1 Orange or 70 ml of Fresh Orange Juice.

How to Make Rhubarb Cordial

Making Cordial is ridiculously easy, you’ll soon wonder why you haven’t done it sooner!

  1. Put all the ingredients in a pan
  2. Simmer for around 15 minutes until all the ingredients become mushy
  3. Take of the heat, pour through a sieve (separating the mush from the syrup)
  4. Store in a bottle in the fridge for up to 1 month.

To taste, dilute with water.

What to do with the leftovers

You will be left with a large amount of mushy Rhubarb. Cover and store in the fridge for up to 3 days. I like to add it to my morning porridge, stir it in yoghurt or combine with Granola….delicious.
