Get 1 cup of water, 1 cup of sugar, 1 packet of jelly powder your favourite flavour and 1 lemon.
In a bowl, mix the jelly powder and sugar together until well combined.
Gradually add in the water, stirring until the mixture is smooth and lump-free.
Add a squeeze of lemon juice to bring out the flavour.
In a saucepan, bring the mixture to a boil, stirring constantly until the sugar dissolves.
Remove from heat and let the mixture cool and set at room temperature.
Once set, your homemade jelly is ready to enjoy. Serve with toast, yoghurt, or as a sweet treat on its own.
