🍓 What Is Rhubarb Syrup?

Rhubarb syrup is a smooth, pourable syrup created by extracting the juice from cooked rhubarb and sweetening it. Unlike compote or jam, the solids are strained out, leaving a clear, pink syrup with a bright flavour.

🧈 Ingredients for Rhubarb Syrup

• Fresh rhubarb stalks
• Water
• Sugar (caster or granulated)

Optional flavourings

• Ginger (fresh slices)
• Vanilla pod or extract
• Orange or lemon peel
• Star anise or cinnamon

🥣 How to Make Rhubarb Syrup

1️⃣ Prepare the Rhubarb

• Wash and trim the rhubarb
• Chop into small, even pieces

2️⃣ Simmer

• Place rhubarb in a saucepan
• Add enough water to just cover
• Bring to a gentle simmer
• Cook for 10–15 minutes, until the rhubarb is very soft

Do not boil hard — gentle heat preserves colour and flavour.

3️⃣ Strain

• Pour the mixture through a fine sieve or muslin
• Let it drip naturally — don’t press, or the syrup may turn cloudy

You should be left with a clear pink liquid.

4️⃣ Sweeten

• Measure the liquid
• Add sugar (typically 1:1 by volume for a classic syrup, or less for a sharper taste)
• Return to the pan and heat gently until the sugar dissolves

5️⃣ Cool and Bottle

• Allow to cool
• Pour into a clean, sterilised bottle or jar
• Seal and refrigerate

⏳ Storage

• Store in the fridge
• Keeps for 2–3 weeks
• For longer storage, freeze in small portions

This is a fresh syrup, not a shelf-stable preserve.

🍹 How to Use Rhubarb Syrup

Rhubarb syrup is incredibly versatile. Use it:

• Mixed with sparkling water or lemonade
• In cocktails or mocktails
• Drizzled over pancakes, waffles, or porridge

🔥 Tips for Perfect Rhubarb Syrup

• Use forced rhubarb for a sweeter, paler syrup

• Keep heat low to protect colour
