Step 1

The best (and simplest!) ratio is 1:1 sugar to water. If you want a sweeter "rich sugar syrup", then use a ratio of 2:1 of sugar to water.

Step 2

Add the sugar and water to a saucepan over medium heat. Bring to a soft boil and stir constantly until the sugar completely dissolves. This will usually take 2-3 minutes. Be careful and keep an eye on the sugar and water so the sugar doesn't burn.

Step 3

Once the sugar has completely dissolved, switch off the heat and allow the syrup to cool before transferring it to a sterilized, airtight glass jar/bottle. The syrup should be thin and easy to pour.

Step 4

Fridge: The classic 1:1 syrup can be stored in the fridge for 3-4 weeks. The rich version using the 2:1 ratio will keep you in the fridge for up to several months. It's also shelf-stable, so you can store it at room temperature if you prefer. If your mixture has turned cloudy, this can mean the simple syrup has spoiled and should be disposed of.
